bump version to 2.0.7

* Bug fix for hostname and base path reversal for command line
  introduced in 2.0.6
* Transformed types are now treated correctly when used in array types

v2.0.6 includes some minor changes

* move user id logging to FINE
* make GoogleAuth#getAuthToken() public so Authenticators can use it
* add hostname and base path flags to all EndpointsTool commands
* hide resource fields that have all private members (instance field,
  accessor, and mutator). Previously, a private mutator would make the
  resource field public.

* Doubles now have a double format in discovery, matching previous
  behavior
* API Explorer redirect has been fixed to remove the port number, which
  API Explorer does not allow in most cases
* Authenticator classes can now throw ServiceException. Exception
  logging from SystemService has been cleaned up and (hopefully)
  improved
* Fix a stack overflow issue when recursive schema are used across
  multiple APIs
* Disable property/field name conflict validation, opting to log instead
  of throw for the time being
* Add API config validation to get-discovery-doc tool action
