Vendor in latest storage, image and runtime-tools

Need to pull in the latest containers/storage and containers/image to fix lots of
issues.  Also want to update runtime-tools to take advantage of newer generate
code.

+## Usage
+
+### Example
+
+```go
+
+package main
+
+import (
+    "fmt"
+    "github.com/xeipuuv/gojsonschema"
+)
+
+func main() {
+
+    schemaLoader := gojsonschema.NewReferenceLoader("file:///home/me/schema.json")
+    documentLoader := gojsonschema.NewReferenceLoader("file:///home/me/document.json")
+
+    result, err := gojsonschema.Validate(schemaLoader, documentLoader)
+    if err != nil {
+        panic(err.Error())
+    }
+
+    if result.Valid() {
+        fmt.Printf("The document is valid\n")
+    } else {
+        fmt.Printf("The document is not valid. see errors :\n")
+        for _, desc := range result.Errors() {
+            fmt.Printf("- %s\n", desc)
+        }
+    }
+
+}
+
+
+```
+
+#### Loaders
+
+There are various ways to load your JSON data.
+In order to load your schemas and documents,
+first declare an appropriate loader :
+
+* Web / HTTP, using a reference :
+
+```go
+loader := gojsonschema.NewReferenceLoader("http://www.some_host.com/schema.json")
+```
+
+* Local file, using a reference :
+
+```go
+loader := gojsonschema.NewReferenceLoader("file:///home/me/schema.json")
+```
+
+References use the URI scheme, the prefix (file://) and a full path to the file are required.
+
+* JSON strings :
+
+```go
+loader := gojsonschema.NewStringLoader(`{"type": "string"}`)
+```
+
+* Custom Go types :
+
+```go
+m := map[string]interface{}{"type": "string"}
+loader := gojsonschema.NewGoLoader(m)
+```
+
+And
+
+```go
+type Root struct {
+	Users []User `json:"users"`
+}
+
+type User struct {
+	Name string `json:"name"`
+}
+
+...
+
+data := Root{}
+data.Users = append(data.Users, User{"John"})
+data.Users = append(data.Users, User{"Sophia"})
+data.Users = append(data.Users, User{"Bill"})
+
+loader := gojsonschema.NewGoLoader(data)
+```
+
+#### Validation
+
+Once the loaders are set, validation is easy :
+
+```go
+result, err := gojsonschema.Validate(schemaLoader, documentLoader)
+```
+
+Alternatively, you might want to load a schema only once and process to multiple validations :
+
+```go
+schema, err := gojsonschema.NewSchema(schemaLoader)
+...
+result1, err := schema.Validate(documentLoader1)
+...
+result2, err := schema.Validate(documentLoader2)
+...
+// etc ...
+```
+
+To check the result :
+
+```go
+    if result.Valid() {
+    	fmt.Printf("The document is valid\n")
+    } else {
+        fmt.Printf("The document is not valid. see errors :\n")
+        for _, err := range result.Errors() {
+        	// Err implements the ResultError interface
+            fmt.Printf("- %s\n", err)
+        }
+    }
+```
+
+## Working with Errors
+
+The library handles string error codes which you can customize by creating your own gojsonschema.locale and setting it
+```go
+gojsonschema.Locale = YourCustomLocale{}
+```
+
+However, each error contains additional contextual information.
+
+**err.Type()**: *string* Returns the "type" of error that occurred. Note you can also type check. See below
+
+Note: An error of RequiredType has an err.Type() return value of "required"
+
+    "required": RequiredError
+    "invalid_type": InvalidTypeError
+    "number_any_of": NumberAnyOfError
+    "number_one_of": NumberOneOfError
+    "number_all_of": NumberAllOfError
+    "number_not": NumberNotError
+    "missing_dependency": MissingDependencyError
+    "internal": InternalError
+    "enum": EnumError
+    "array_no_additional_items": ArrayNoAdditionalItemsError
+    "array_min_items": ArrayMinItemsError
+    "array_max_items": ArrayMaxItemsError
+    "unique": ItemsMustBeUniqueError
+    "array_min_properties": ArrayMinPropertiesError
+    "array_max_properties": ArrayMaxPropertiesError
+    "additional_property_not_allowed": AdditionalPropertyNotAllowedError
+    "invalid_property_pattern": InvalidPropertyPatternError
+    "string_gte": StringLengthGTEError
+    "string_lte": StringLengthLTEError
+    "pattern": DoesNotMatchPatternError
+    "multiple_of": MultipleOfError
+    "number_gte": NumberGTEError
+    "number_gt": NumberGTError
+    "number_lte": NumberLTEError
+    "number_lt": NumberLTError
+
+**err.Value()**: *interface{}* Returns the value given
+
+**err.Context()**: *gojsonschema.jsonContext* Returns the context. This has a String() method that will print something like this: (root).firstName
+
+**err.Field()**: *string* Returns the fieldname in the format firstName, or for embedded properties, person.firstName. This returns the same as the String() method on *err.Context()* but removes the (root). prefix.
+
+**err.Description()**: *string* The error description. This is based on the locale you are using. See the beginning of this section for overwriting the locale with a custom implementation.
+
+**err.Details()**: *gojsonschema.ErrorDetails* Returns a map[string]interface{} of additional error details specific to the error. For example, GTE errors will have a "min" value, LTE will have a "max" value. See errors.go for a full description of all the error details. Every error always contains a "field" key that holds the value of *err.Field()*
+
+Note in most cases, the err.Details() will be used to generate replacement strings in your locales, and not used directly. These strings follow the text/template format i.e.
+```
+{{.field}} must be greater than or equal to {{.min}}
+```
+
+The library allows you to specify custom template functions, should you require more complex error message handling.
+```go
+gojsonschema.ErrorTemplateFuncs = map[string]interface{}{
+	"allcaps": func(s string) string {
+		return strings.ToUpper(s)
+	},
+}
+```
+
+Given the above definition, you can use the custom function `"allcaps"` in your localization templates:
+```
+{{allcaps .field}} must be greater than or equal to {{.min}}
+```
+
+The above error message would then be rendered with the `field` value in capital letters. For example:
+```
+"PASSWORD must be greater than or equal to 8"
+```
+
+Learn more about what types of template functions you can use in `ErrorTemplateFuncs` by referring to Go's [text/template FuncMap](https://golang.org/pkg/text/template/#FuncMap) type.
+
+## Formats
+JSON Schema allows for optional "format" property to validate instances against well-known formats. gojsonschema ships with all of the formats defined in the spec that you can use like this:
+````json
+{"type": "string", "format": "email"}
+````
+Available formats: date-time, hostname, email, ipv4, ipv6, uri, uri-reference.
+
+For repetitive or more complex formats, you can create custom format checkers and add them to gojsonschema like this:
+
+```go
+// Define the format checker
+type RoleFormatChecker struct {}
+
+// Ensure it meets the gojsonschema.FormatChecker interface
+func (f RoleFormatChecker) IsFormat(input interface{}) bool {
+
+    asString, ok := input.(string)
+    if ok == false {
+        return false
+    }
+
+    return strings.HasPrefix("ROLE_", asString)
+}
+
+// Add it to the library
+gojsonschema.FormatCheckers.Add("role", RoleFormatChecker{})
+````
+
+Now to use in your json schema:
+````json
+{"type": "string", "format": "role"}
+````
+
+Another example would be to check if the provided integer matches an id on database:
+
+JSON schema:
+```json
+{"type": "integer", "format": "ValidUserId"}
+```
+
+```go
+// Define the format checker
+type ValidUserIdFormatChecker struct {}
+
+// Ensure it meets the gojsonschema.FormatChecker interface
+func (f ValidUserIdFormatChecker) IsFormat(input interface{}) bool {
+
+    asFloat64, ok := input.(float64) // Numbers are always float64 here
+    if ok == false {
+        return false
+    }
+
+    // XXX
+    // do the magic on the database looking for the int(asFloat64)
+
+    return true
+}
+
+// Add it to the library
+gojsonschema.FormatCheckers.Add("ValidUserId", ValidUserIdFormatChecker{})
+````
