LDAP Sync: Re-add ldap users to channels and teams

There are 2 options when you need to re-sync users.

Option 1

mmctl ldap sync --include-removed-members

This command will re-sync all users to their group synced teams and channels. Useful in cases where synchronized groups are unlinked/re-linked for testing purposes, when LDAP users are deactivated and reactivated, or when a user leaves a team in error.

Option 2

You can sync individual users in System Console by navigating to users, clicking the actions button and then Re-sync user via LDAP groups.
