OCP Version:
4.10.0-0.nightly-2022-02-07-032308

How reproducible:
Always

Steps to Reproduce:
Create an OVN cluster
Scaleup a RHEL machine

Actual results:
New RHEL machine not ready

Expected results:
Scaleup finished successfully

Suggestion:
Avoid to use jq tool in configure-ovs.sh script
Or update documents that mention the jq tool is required for scaleup RHEL machines.

Additional info:
After installing jq tool in RHEL machine before doing scaleup, the scaleup process finished successfully.
