Set podSecurityContext for the dragonfly custom resource

[sisrael-dn]

Hello,

Right now the dragonfly crd doesn't seem to support setting any podSecurityContext (correct me if I'm wrong) which will be passed for the pods running dragonfly.
Would it it possible to add this please?

So We can create for example something like:

apiVersion: dragonflydb.io/v1alpha1
kind: Dragonfly
metadata:
  labels:
    app.kubernetes.io/name: dragonfly-sample
    app.kubernetes.io/instance: dragonfly
    app.kubernetes.io/part-of: dragonfly-operator
    app.kubernetes.io/managed-by: helm
    app.kubernetes.io/created-by: dragonfly-operator
  name: dragonfly-sample
spec:
  podSecurityContext:
    capabilities:
      add: ["IPC_LOCK"]

Hey @sisrael-dn, You are right that we don't support setting podSecurityContext through Dragonfly resource for Dragonfly pods.

This isn't a high priority right now, Can you raise a PR to add this configuration into https://github.com/dragonflydb/dragonfly-operator/blob/main/api/v1alpha1/dragonfly_types.go#L28

Hi @Pothulapati , I understand, thank you for pointing me to the right place to add it.
I'll try to raise a PR as suggested when I'll have some free time (:

This will be needed to fix Weird error 1 switching to epoll

dragonflydb/dragonfly#4042

Or maybe not?
