client:side: automatic validation of outgoing requests and incoming responses

[karenetheridge]

Like #5, but for the client, so something in Mojo::UserAgent.

• configurable, with callbacks for how to handle validation failure
• the default here would be that invalid outgoing requests should signal a logging error, potentially fatal if in a development or testing system, and failures on incoming responses would be processed on a best-effort basis with the error logged.
• store the openapi document on the useragent; results can be stored on the tx and therefore shared with the Test::Mojo role
• automatic validation can be added with event hooks ('start' in Mojo::UserAgent for processing the request and setting up the hook to receive the response: on 'finish' in Mojo::Transaction for processing the response)

Hey, thanks for this project! I finally got around to doing some web development last night and tried out this plugin. It really does solve a lot of the issues I had when implementing the alternative. One thing though, and I think this ticket touches on it: I'm looking for a client.
