Addressed issues

The following issue has been resolved in the MSR 3.0.6 patch release:

• [FIELD-5447] Fixed an issue with the /api/v0/api_tokens endpoint wherein changing the value of the pageStart parameter did not change the page returned in the request output.

  When upgrading from a previous MSR version, for the fix to go into effect you must run a particular command sequence using the RethinkDB CLI. Contact Mirantis support for the RethinkDB CLI instructions. Fresh installations do not require the manual CLI steps.
