Refactor the API request method for use in specs

DRY'ing up the request handler a little bit to allow the CLI
application and the specs to use the same handler instead of two
seperate ones.
Added moar coverage for all classes
Fix syntax error for variable assignment
Updating delete database spec to include new changes
Declared a static string for the database name

VCR does a strict comparison on the body attribute to determine whether
it is the same request or not and due to the database name being
dynamically generated, that check keeps failing.
No need to assign the response as it isn't used
Add in guard and rspec
Ignore temporary guard file directory
Documentation update for methods
Split the db_clusters by commas instead of an array
Updated wording in auth spec
Remove guard dependency - It is just nice to have
Adding spec cassettes
DRY'ing up specs
Add in new helper methods for specs
Cleaned up helper documentation
Cleaning up more VCR cassettes
Updating contributing notes
Space it out
Removing extra JSON.parse calls in the request handler
