Enable automatic repository->Jira project entity link creation

Currently any application links between Fisheye and Jira must be manually created. This can be a tedious process when multiple Jira projects are referenced by commit messages in multiple repositories.

Once the basic application link to Jira is set up, Fisheye is fully aware of the list of projects that Jira has. This combined with the index of commit messages that Fisheye builds should allow it to automatically create application links between Fisheye repositories and Jira projects, saving admins time and effort.

Security is covered by proper configuration of Jira project permissions schemes and per-repository access settings on the Fisheye side
