On our dev instance, /admin/applications as not loading because:

1. There was an unindexed query by `application_id`.
2. There was an expensive query that attempted to load 1 million
   unique entries via ActiveRecord just to find the unique count.

We fix the first issue by adding an index for that column.

We fix the second issue with a simple SELECT COUNT(DISTINCT
resource_owner_id) SQL query.

In addition, we add pagination to avoid loading more than 20
applications at once.

- Update unit tests and e2e tests to reflect these changes

creating dynamic code to remove duplciation.

It seems that we missed the backward compatibility support
for profiles in the existing folder.

This commit also fixes some specs to be idempotent
and work in a temporary directory which not always
seems to be the case.

This commit also brings the profile_spec.rb which seems
to be missing.

This change adds audit logs for user impersonation
when an admin starts/stops impersonating
another user.

- Migration updates existing groups to "owner", then sets default to
  "maintainer" so that new groups will default to that
- Update spec examples
