GDPR changes in Jira Cloud REST Api

Atlassian had made changes to Jira Cloud in order to improve user privacy in accordance with the European General Data Protection Regulation (GDPR).

One of the changes that affected TFS4JIRA Synchronizer is removal of Username field from Jira Cloud REST-API, and replacing it with a new user identifier - Account ID.

TFS4JIRA Synchronizer up to version 7.6 used the Username field to map users between Jira Cloud and TFS.
The versions 7.7 and above adapt to the above mentioned changes and use the new mechanism to map users.
