[bitnami/common] Option to add "app.kubernetes.io/component" label

[bonddim]

Description of the change

Provide option for labels templates to include app.kubernetes.io/component label

Benefits

Reduce code duplication in multi-component charts.

For example:

spec:
  selector:
    matchLabels: {{- include "common.labels.matchLabels" ( dict "customLabels" $podLabels "context" $ ) | nindent 6 }}
      app.kubernetes.io/component: controller
  template:
    metadata:
      labels: {{- include "common.labels.standard" ( dict "customLabels" $podLabels "context" $ ) | nindent 8 }}
        app.kubernetes.io/component: controller

Could be changed to:

spec:
  selector:
    matchLabels: {{- include "common.labels.matchLabels" ( dict "customLabels" $podLabels "context" $ "component" "controller" ) | nindent 6 }}
  template:
    metadata:
      labels: {{- include "common.labels.standard" ( dict "customLabels" $podLabels "context" $ "component" "controller") | nindent 8 }}
