switch to use new K8s control-plane label

Upstream has deprecated 'node-role.kubernetes.io/master'
to use 'node-role.kubernetes.io/control-plane' in k8s 1.24.

Platform and applications need to be updated to use 'control-plane'
with nodeSelector/Tolerations so we may upgrade from 'master'.

This updates pod nodeSelector to use
'node-role.kubernetes.io/control-plane' instead of
'node-role.kubernetes.io/master'.

This updates pod Tolerations to support both:
- 'node-role.kubernetes.io/master'
- 'node-role.kubernetes.io/control-plane'

Note: The vault app stopped applying properly when stx moved to k8s 1.22
      1.23 due to the use of deprecated APIs:
      https://github.com/hashicorp/vault-helm/blob/v0.6.0/templates/injector-mutating-webhook.yaml#L2
      https://github.com/hashicorp/vault-helm/blob/v0.6.0/templates/server-clusterrolebinding.yaml#L4
      The changes will still be merged to ensure that the files are
      updated when updating vault to a new version which is compatible
      w/ k8s 1.24+
