Remove ulele/deepcopier in favor of JSON deep copy

We have a very high performance JSON library that doesn't need to
perform code generation. Let's use it instead of our questionably
performant, reflection-dependent deep copy library.

Most changes because some functions can now return errors.

Also converts cmd/podman to use jsoniter, instead of pkg/json,
for increased performance.

-# Deepcopier
-
-[![Build Status](https://secure.travis-ci.org/ulule/deepcopier.png?branch=master)](http://travis-ci.org/ulule/deepcopier)
-
-This package is meant to make copying of structs to/from others structs a bit easier.
-
-## Installation
-
-```bash
-go get -u github.com/ulule/deepcopier
-```
-
-## Usage
-
-```golang
-// Deep copy instance1 into instance2
-Copy(instance1).To(instance2)
-
-// Deep copy instance1 into instance2 and passes the following context (which
-// is basically a map[string]interface{}) as first argument
-// to methods of instance2 that defined the struct tag "context".
-Copy(instance1).WithContext(map[string]interface{}{"foo": "bar"}).To(instance2)
-
-// Deep copy instance2 into instance1
-Copy(instance1).From(instance2)
-
-// Deep copy instance2 into instance1 and passes the following context (which
-// is basically a map[string]interface{}) as first argument
-// to methods of instance1 that defined the struct tag "context".
-Copy(instance1).WithContext(map[string]interface{}{"foo": "bar"}).From(instance2)
-```
-
-Available options for `deepcopier` struct tag:
-
-| Option    | Description                                                          |
-| --------- | -------------------------------------------------------------------- |
-| `field`   | Field or method name in source instance                              |
-| `skip`    | Ignores the field                                                    |
-| `context` | Takes a `map[string]interface{}` as first argument (for methods)     |
-| `force`   | Set the value of a `sql.Null*` field (instead of copying the struct) |
-
-**Options example:**
-
-```golang
-type Source struct {
-    Name                         string
-    SkipMe                       string
-    SQLNullStringToSQLNullString sql.NullString
-    SQLNullStringToString        sql.NullString
-
-}
-
-func (Source) MethodThatTakesContext(c map[string]interface{}) string {
-    return "whatever"
-}
-
-type Destination struct {
-    FieldWithAnotherNameInSource      string         `deepcopier:"field:Name"`
-    SkipMe                            string         `deepcopier:"skip"`
-    MethodThatTakesContext            string         `deepcopier:"context"`
-    SQLNullStringToSQLNullString      sql.NullString 
-    SQLNullStringToString             string         `deepcopier:"force"`
-}
-
-```
-
-Example:
-
-```golang
-package main
-
-import (
-    "fmt"
- 
-    "github.com/ulule/deepcopier"
-)
-
-// Model
-type User struct {
-    // Basic string field
-    Name  string
-    // Deepcopier supports https://golang.org/pkg/database/sql/driver/#Valuer
-    Email sql.NullString
-}
-
-func (u *User) MethodThatTakesContext(ctx map[string]interface{}) string {
-    // do whatever you want
-    return "hello from this method"
-}
-
-// Resource
-type UserResource struct {
-    DisplayName            string `deepcopier:"field:Name"`
-    SkipMe                 string `deepcopier:"skip"`
-    MethodThatTakesContext string `deepcopier:"context"`
-    Email                  string `deepcopier:"force"`
-
-}
-
-func main() {
-    user := &User{
-        Name: "gilles",
-        Email: sql.NullString{
-            Valid: true,
-            String: "gilles@example.com",
-        },
-    }
-
-    resource := &UserResource{}
-
-    deepcopier.Copy(user).To(resource)
-
-    fmt.Println(resource.DisplayName)
-    fmt.Println(resource.Email)
-}
