Merge remote-tracking branch 'upstream/master' into git-post-commit-hook
Merge pull request #212 from bsharanya/master

Workaround for specs to pass.
Removing unused filter code. AuthenticationFilter was getting user object from DB and performing license operations with it.

Enclosing debug logs with isDebugEnabled to prevent String object construction when unnecessary.
#190 - Adding validators to check for url equality when basic auth is provided with git url
