Update: Ensure parallel execution 

In middle of Queens and Rocky release we introduced option to
set parallel execution of minor update on selected role types.
If the environment went through FFWD or was deployed before this
option got backported we need to update the roles_data.

By default we have update_serial either unset at all for OSP13 and OSP14 or
we have it set where Pacemaker enabled nodes, CephOSD nodes and Networkers
have it set to 1. This is mostly defensive precaution and we do allow running
in parallel for CephOSD and Networkers for production systems that did enough
testing on preprod or can take small outage. We should also parallelize it in
CI as we just waste time here.
