Api documentation fixes (#2646)

* Fix the API documentation for Chain Validate (v1/chain/validate).  It was documented as a POST, but it is actually a GET request, which can be seen in its handler ChainValidationHandler
* Update the API V1 route list response to include the headers and merkleproof routes.  Also clarify that for the chain/outputs route you must specify either byids or byheight to select outputs.
