[RFE] Replace deprecated wsme library with alternative

[Madhuri Kumari]

Currently ironic uses wsme to validate input parameters which is no longer maintained[1][2]

One option is to use jsonschema (https://pypi.python.org/pypi/jsonschema). A jsonschema validator object can be used to check each resource against an appropriate schema for that resource. If the validation passes, the request can follow the existing flow of control to the resource manager to the backend. If the request body parameters fail the validation specified by the resource schema, a validation error will be returned from the server.

I've marked this as an RFE; I agree that in theory it could be a bug but IMO it needs enough design that we should treat it like an RFE and have a spec written. Can you please lay out your proposed changes in a spec so that the cores can agree on the solution? This would be a major change in our API code :).

@Jay, thanks for confirming this bug. I will submit a spec soon.

Reason: This effort has been already approved and is currently under way. There is no need for a spec at this point (but thank you for writing it!).
