refactor(cmd-api-server): pull OAuth2 endpoint scopes from openapi.json

Primary Changes
----------------
1. added OAuth2 security endpoints scopes to openapi.json
2. added a test to make sure if the scopes are indeed getting
   pulled from the spec file

Fixes #2693

1. Please also refactor the third endpoint (prometheus metrics) accordingly
2. Also please extend the test case with each tokens having specific scopes
and then assert that the tokesn with the correct scopes work and the ones
that don't have the correct scopes do not even when they are otherwise
valid tokens.
