make jiraLocation compatible with git interpret-trailers

[tamasd]

If jiraLocation could put the issue ID to the end of the body in a key-value like format, then git interpret-trailers could understand it. This would make processing the commit message with scripts easier.

It would be great if the JIRA's URL could be specified with the config as well, so a commit message could look like this:

fix(foo): baz no longer produces invalid value

JIRA-ID: ASDF-1234
JIRA-Link: https://my-jira-instance.example.com/browse/ASDF-1234

I would welcome a PR that does this but I am not sure of how useful that is. If you look at cz-conventional-changelog that this project forks from, you get almost that functionality. The reason for creating our fork is that we wanted the issue in the commit message. It looks like this:

fix(foo): baz no longer produces invalid value

fixes ASDF-1234

It is not exactly what you ask for, and our tool still has one additional functionality (automatic issue detection) but do you think it's enough for your use case?
