Permanently assigned translator

Link to original bug (#568770)
Description
Some translation teams want to use a bit different workflow than the current Vertimus offers:
Coordinator first assign a translator to the module. After that the translator become a module translation maintainer and only this translator is able to translate (and submit) new translations of the module.
Coordinator could reassign the module to another translator if needed. The current permanently assigned translator should be visible somehow somewhere.
