Storage cluster creation page

Description of problem:
-------------------------------
With OCP 4.7 (flexible scaling) is introduced where, if we have zone length less than 3 then following warning is enabled on the screen:

>>Warning alert:The number of selected zones is less than the minimum requirement of 3. If not modified, a host-based failure domain deployment will be enforced.

But for platforms like VMware and Bare metal where there are racks instead of a zone, we need to handle this warning differently, as zones are expected to be 0. Seeing this warning can be confusing to users for platforms which do not use zone explicitly.


Version-Release number of selected component (if applicable):
-------------------------------------------------------
OCP version - 4.7.0-0.nightly-2020-12-14-165231
OCS version - 4.7.0-198.ci

How reproducible:
-------------------
Always

Steps to Reproduce:
-----------------------
1. Install OCP 4.7 on say VMware which uses racks rather than zones
2. Install OCS operator 4.7 
3. Click on Create Storage cluster and the attached page is displayed


Actual results:
------------------
Even for vmware where zones are NA, the warning is displayed which is confusing for the user

Warning alert:The number of selected zones is less than the minimum requirement of 3. If not modified, a host-based failure domain deployment will be enforced.

Expected results:
--------------------
It should be handled differently for platforms which use racks



Additional info:
---------------------

Also, how will it affect 1 AZ AWS clusters? it will show the warning and that is expected.. right ?

This is a valid message as discussed. We agreed to soften the visual if possible. 

Zones expected in VMWare and BMO with stretch cluster (with or without Arbiter). 
Also, will be used between racks.

sounds good @afrahman
