chore(bors): merge pull request #802

802: fix: normalize release name for alloy (backport #800) r=tiagolobocastro a=mergify[bot]

This PR fixes the release name for alloy. Since Alloy identifiers don't allow hyphen as per the identifier rules. Since release names of helm charts can contain hyphen we handle it by replacing hyphen with underscore.

Testing:
Tested it by creating a helm release with the name "openebs-mayastor". 
The alloy pods were seen in crashloopbackoff state.
Performed a helm upgrade after doing the required changes in values.yaml. 
Verified that the alloy pods were in running state.

Docs_Update:
No Changes Required.<hr>This is an automatic backport of pull request #800 done by [Mergify](https://mergify.com).
