API Schema Generation

[youkaicountry]

Output automatically generated schema for each API call.

Acceptance Criteria:

• JSON formatted output
• Output should include call, params, and return

[mvandeberg]

The API itself is already self-describing.

There are two api calls, get_methods and get_signature. get_methods returns a list of all registered API calls on the node and get_signature returns default initialized arg and return types for a particular method. Using these you can generate a JSON schema for the all available API calls on a particular node.

For most API calls, this adequately describes the call. The only place this fails short are arguments that include opaque types such as static_variant, variant, vector, flat_map, etc. This also does not return any primitive type information, although it may be possible to leverage information already captured by FC's reflection to do this.
