Adding new job to test for the last supported version of kubernetes

[harshavardhana]

question why on these k8s versions?

Hi @harshavardhana today while testing for the PR #1278 we identified the helm chart update doesn't work with Kubernetes 1.21 version but works with 1.25, since many of the customers still use 1.20 we wanted to ensure we didn't break anything in operator codebase.

Hi @harshavardhana today while testing for the PR #1278 we identified the helm chart update doesn't work with Kubernetes 1.21 version but works with 1.25, since many of the customers still use 1.20 we wanted to ensure we didn't break anything in operator codebase.

So should we simply deprecate helm chart for k8s v1.21 and older ?

@harshavardhana after discussing this with Ab, we are going to keep the support for 1.20 around for a little longer, so we should take this in and delay the breaking changes to Helm until k8s 1.26 lands, then we can move our floor to 1.21

[dvaldivia]

We should take this @harshavardhana since we are going to be adding support for container level SecurityContext in a backwards compatible way, we need to make sure testing on our floor release is still working.

Also with the release of v1.26 we should make v1.21 the floor release @dilverse

Done bumped the version to 1.21.14

Why do we need to squash the commits?
When the PR is getting merged its anyway going to squash and merge right?

I know it's a good practice but we are already doing it during merge... why do it twice and dismiss previous approvals?

Ok guys you are right, I haven't think that way but you are right, why do it twice 👍
