Remove passed freshmen from the 10weeks ldap group after passing 10 weeks

There is now a `10weeks` ldap group, to help show and determine who is currently in the 10 weeks process to services. Members should be removed from this upon passing a 10 weeks but remain in the `intromembers` group until they pass a spring evaluations

No file or test is named in the issue. Start by locating the Python code that manages the `10weeks` and `intromembers` LDAP groups, then trace how members pass the 10-week process. Done means a member is removed from `10weeks` after passing while remaining in `intromembers` until spring evaluations.
