1657 - activity "User" filter should accept usernames instead of owner_ids

[Vladysl]

BE:

1. added new endpoint GET /api/activity/users - should be used to retrieve usernames, which present in activity table.
2. Updated /api/activity/counts, /api/dataentities/{data_entity_id}/activity and /api/activity - now accepting array of String instead of owner_ids for users.

FE:

1. need to update /api/activity/counts, /api/dataentities/{data_entity_id}/activity and /api/activity API's
2. make request GET /api/activity/users to retrieve usernames on DataEntity-> Activity and Activity Tabs
