Get list of issue assignee candidates through REST API (BB-10371)

Issue #9293 open

When communicating with Bitbucket through REST, there is no way to get a list of possible assignees for an issue (see https://confluence.atlassian.com/display/BITBUCKET/issues+Resource?focusedCommentId=311919730#comment-311919730).

It would be nice to know who it is possible to assign an issue to, and the website already gives us a dropdown list, so the figuring out routine is already there. Cannot be very hard to implement, in my opinion.
