  [#3005] Add model and API for following groups

This implements everything required at the model and API level for following
and unfollowing of groups, getting a group's number of followers or a list of a
group's followers, and getting the number of groups that a user follows or a
list of the groups that a user follows.

Tests need to be added.

Frontend for following groups needs to be added.

+ Add UserFollowingGroup model class and user_following_group_dictize().

+ Add "{actor} started following {group}" activity stream activity.

+ Refactor user_following_user_dict_save() and
  user_following_dataset_dict_save(), replace with a single
  follower_dict_save() that can be used for UserFollowingUser,
  UserFollowingDataset, or UserFollowingGroup.

+ Add follow_group() and unfollow_group() logic action functions in create.py
  and delete.py.

+ Add group_follower_count(), group_follower_list(), am_following_group(),
  group_followee_count() and group_followee_list() logic action functions in
  get.py.

  Also refactor some code in logic/action/get.py to remove duplication between
  follower functions.

+ Add convert_group_name_or_id_to_id() converter function

+ Add default_follow_group_schema()

+ Add migration script
