[RFC] Jira hooks redesigned on Gerrit 2.6 commit validation.

Completely new redesigned version of Jira hooks with
a common reusable infrastructure to build the issue-tracking
association logic to other Issue-Trackers (i.e. BugZilla).

Depends on the generic issue-tracker association 
maven module "hooks-its" which provides the logic for:
> Insertion of comment links using regex patterns
> Enforcement of issue-ids in git commits using
  Gerrit 2.6 commit validation listeners
> Automation of issue-tracker status transition 
  based on Gerrit code-review status

The hooks-jira layer provides the implementation of
the ItsFacade and the init-step to configure and
check connectivity with Atlassian Jira.
