awx-operator Add 'labels' to the Helm chart to simplify the declaration of labels

SUMMARY

Add labels to the Helm chart to simplify the declaration of custom labels.

ISSUE TYPE

New or Enhanced Feature

ADDITIONAL INFORMATION

This change allows the labels defined in the additional_labels parameters to be specified in the same values.xml file.
These labels are also added to the awx-operator-controller-manager pod. Useful when labels are used to control pod creation based on label rules.

Sample of values.xml

AWX:
  enabled: true
  labels:
    my/team: "foo"
    my/service: "bar"
    my/do-not-inherit: "yes"
  name: awx
