Description Brett Thurber 2021-11-01 15:46:32 UTC

Description of problem:
SRO was not adjusted to SNO API behavior - aka, it's leader election lease is 15s (which will cause it to be restarted in case of api rollout on SNO). 

Version-Release number of selected component (if applicable):
4.9

How reproducible:
Every time

Steps to Reproduce:
1. Deploy SRO in SNO
2.
3.

Actual results:
SRO restarts when deployed on SNO which can cause OOT driver container loading and ordering issues.

Expected results:
SRO handles longer timeout to support SNO API availability.
