Code Issues Proposed changes

Credentials#unset method

Browse Source 
* Unset was broken, not resetting the variables
* Also added a rspec example

It worked but wasn't clean as if an authentication method failed some fields
could have been left un-blanked, creating bad side effects.

In addition:
* Added tests for #set with both valid and invalid values
* Added negative tests for #service_token_set? and user_password_set?
* Added test for #version
* Fixed #unset test
* Fixed #to_env test
* In several tests, added an OS_NOT_VALID parameter to make sure the
  credentials code correctly ignores it
* Added tests to make sure the fallback in Auth.request works properly
* Added additional tests to make sure the @credentials object is set
  correctly
* Fixed some formatting/alignment issues
