STX-Openstack | Hypervisor slow to go back up

[Gabriel Calixto de Paula]

Brief Description
-----------------
During a sanity run with STX rc 7.0 latest_build with STX-Openstack, when running tests that wait for the hypervisor to come back up, it's slow to come back, causing them to fail, even after increasing the time from 5 to 10 minutes.

Minor

Steps to Reproduce
------------------
1. Run STX+STX-O sanity job
Expected Behavior
------------------
It should execute all of the tests without a failure caused by the hypervisor

Actual Behavior
----------------
Tests fail because the hypervisor doesn't come back up
Reproducibility
---------------
Reproducible

System Configuration
