Support for handling username collisions between remote clusters. Users belonging to remote clusters have their username changed to include the remote name e.g. wiggin becomes wiggin:mattermost. @mentions are also modified so the munged username is replaced with the original username when the post is sync'd with the remote the user belongs to. When adding remote users: - append the remote name to the username with colon separator - append the remote name to the email address with colon separator - store the original username and email address in user props - when resolving @mentions replace with the stored original username
