Add user mapping by username to Bitbucket Server importer

Merged Vladimir Ten requested to merge 218609-bitbucket-server-importer-by-slug into master

What does this MR do?

This MR adds optional usermapping by username to Bitbucket Server importer to allow some users to map users by username, when email is not available. This case can happen when migrating over from air gapped bitbucket server (behind firewall) to an intermediate proxy gitlab/bitbucket server where you lose some of the data on the way. Having optional usermapping by username should still allow users to migrate over their data with correct users assigned.
