Yes

If this is a regression, please provide more details to justify this:
NA

Steps to Reproduce:
1.Install 6 worker node cluster and label the worker nodes in 6 different racks
2. When more than five, say six failure domains are present wait for CephMonLowNumber alert.
3. Upon inspecting the alert message 'The number of zone failure domains available  (5) allow to increase the ceph monitors from 3 to 5 in order to improve cluster resilience'


Actual results:
The alert has hard coded value of failure domains available in 'The number of zone failure domains available  (5) allow to increase the ceph monitors from 3 to 5 in order to improve cluster resilience'

Expected results:
'The number of zone failure domains available  (5) allow to increase the ceph monitors from 3 to 5 in order to improve cluster resilience' failure domain value should not be hardcoded
