get api for given method

There are two ways how this method can be used: 1) Specify both parameters

resource_name:
    controller class - UsersController
    string with resource name (plural) and version - "v1#users"
method_name: name of the method (string or symbol)

2) Specify only first parameter:

resource_name: string containing both resource and method name joined
with '#' symbol.
- "users#create" get default version
- "v2#users#create" get specific version
