Jira integration

Fix #59

[ar4ntic]

Many thanks for your contribution, @carlosreig. The Jira integration is currently an enterprise feature, but I’m seeing increasing demand for it from the community and agree that it should be added to the open-source editions.

However, in order to merge your PR, you need to sign off your commits.

Sign Your Work
We use the Developer Certificate of Origin (DCO) as an additional safeguard for the BugPin project. This is a well-established and widely used mechanism to assure contributors have confirmed their right to license their contribution under the project's license.

Please read the DCO file. If you can certify it, then just add a line to every git commit message:

Signed-off-by: Your Name <your.email@example.com>

Use your real name (sorry, no pseudonyms or anonymous contributions). You can sign your commit automatically with git commit -s. You can also use git aliases like git config --global alias.ci 'commit -s'. Now you can commit with git ci and the commit will be signed.

Please see CONTRIBUTING.md for further information.
