Description of problem:
`Volume Set Name` field does not conform to the DNS label standards (https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#dns-label-names). So entering an invalid names leads to failure in LocalVolumeSet.

Version-Release number of selected component (if applicable):
OCS 4.6 
LSO 4.6

How reproducible:
Every time

Steps to Reproduce:
1.Install LSO 4.6 on OCP 4.6
2.Install OCS 4.6
3.In `Internal-attached Devices>Step2:Create Storage Class` enter `Volume Set Name` with caps, say `LOCALBLOCK`. 

Actual results:
LocalVolumeSet fails with error 
Error "Invalid value: "LOCALBLOCK": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')" for field "metadata.name".


Expected results:
`Volume Set Name` field should conform to the DNS label standards
