ChefAdapterImpl Junits

-Added new Unit tests for ChefAdapterImpl#trigger method
-Refactored ChefAdapterFactory to allow mock injection
-Added new create() method to ChefApiClientFactory which does not set
any Chef specific headers for the purpose of trigger method
-Cleaned up the trigger method - simplified usage, removed useless doFailure
method and inlined its logic and unified HttClient usage -> HttpClient is not
used directly but through existing ChefApiClient
-removed redundant TestChefAdapterImpl tests which have already been rewritten
