Restart QDR after changing the password (#530)

* Restart QDR after changing the password

* Fixes bug reported here: #517 (comment)
* Avoids an extra manual step when changing password
* Would affect users who upgrade from earlier STF and subsequently enable basic auth
* Also users who need to change their passwords

* Fixing ansible lint

* Update roles/servicetelemetry/tasks/component_qdr.yml

* Adjust QDR restarts to account for HA

* [smoketest] Wait for qdr-test to be Running

* [smoketest] Wait for QDR password upgrade

* Remove zuul QDR auth override
