Refactored routing, added more endpoints and types

* Encapsulated all the routing information in the handler_* files.
* Added more serviceapi/types, including podman additions. See Info

Signed-off-by: Jhon Honce <jhonce@redhat.com>

Cleaned up code, implemented info content

* Move Content-Type check into serviceHandler
* Custom 404 handler showing the url, mostly for debugging
* Refactored images: better method names and explicit http codes
* Added content to /info
* Added podman fields to Info struct
* Added Container struct

Add a bunch of endpoints

containers: stop, pause, unpause, wait, rm
images: tag, rmi, create (pull only)

Signed-off-by: baude <bbaude@redhat.com>

Add even more handlers

* Add serviceapi/Error() to improve error handling
* Better support for API return payloads
* Renamed unimplemented to unsupported these are generic endpoints
  we don't intend to ever support.  Swarm broken out since it uses
  different HTTP codes to signal that the node is not in a swarm.
* Added more types
* API Version broken out so it can be validated in the future

serviceapi errors: append error message to API message

I dearly hope this is not breaking any other tests but debugging
"Internal Server Error" is not helpful to any user.  In case, it
breaks tests, we can rever the commit - that's why it's a small one.

Split handlers and server packages

The files were split to help contain bloat. The api/server package will
contain all code related to the functioning of the server while
api/handlers will have all the code related to implementing the end
points.

api/server/register_* will contain the methods for registering
endpoints.  Additionally, they will have the comments for generating the
swagger spec file.

See api/handlers/version.go for a small example handler,
api/handlers/containers.go contains much more complex handlers.
