Fixes test_page_scroll_on_thread_change_view failing on chrome

do orphan deletion in a bulk operation (SUST-21)

There are 3 main changes in this commit:
* CohortFactory now sets up memberships properly, so consuming tests do not
need to explicitly touch CourseUserGroup.users to add() users.
* test_get_cohort_sql_queries has been updated to 3 and 9 queries when using
and not using the cache, respectively. This is needed due to each operation
needing an extra queery to get the CourseUserGroup from the CohortMembership.
* Adding remove_user_from_cohort(), the counterpart to add_user_to_cohort().
This is also to keep tests from touching the users field directly, and keep
CohortMembership data in sync.

An issue arose recently due to ATOMIC_REQUESTS being turned on by default. It
turns out that CohortMemberships had been somewhat relying on the old default
transaction handling in order to keep CohortMemberships and the underlying
CourseUserGroup.users values in-sync.

To fix this, I've made all updates to Cohortmemberships go through an
outer_atomic(read_committed=True) block. This, is conjunction with the already
present select_for_update(), will no longer allow 2 simultaneous requests to
modify objects in memory without sharing them. Only one process will be
touching a given CohortMembership at any given time, and all changes will be
immediately comitted to the database, where the other process will see them.

I've also included some changes to get_cohort(), add_user_to_cohort(), and
remove_user_from_cohort() in order to properly make use of the new
CohortMembership system.
