Require issue keys in commit messages: restrict on regexp per repository

Hello,

currently the "Require issue keys in commit messages" adds a default check on regexp for jira issues from the link:
(((?P<linker_value>([\w-]+))-\d+))
This regex is not changeable. Adding new link with other regex is ignored.

It would be great if the regex check on valid Jira issues is configurable for each repository. e.g.:
repository 1 -> valid allowed issue key: ABC-\d+
repository 2 -> valid allowed issue key: XYZ-\d+

All other jira issue matching default regex should not be allowed.
