Add ability to customise pod annotations

[artemiyplotnikov]

Please add ability to customise pod annotations for deployment k8s-image-availability-exporter
for example:

  template:
    metadata:
      {{- if .Values.k8sImageAvailabilityExporter.annotations }}
      annotations:
       {{- include .Values.k8sImageAvailabilityExporter.annotations . | nindent 8 }}

@artemiyplotnikov sure, but can you elaborate on why you need this? (This is important to know usescases for features).

First of all we use annotations for filtering and configuring scraping options.
For example:

      annotations:
        prometheus.io/scrape: 'true'
        prometheus.io/port: "{{ .Values.env.PROMETHEUS_PORT }}"

I know that there is another options to configure Prometheus scrape but it would multiply configuring options and hardenes

now we use patch for deployment to workaround this problem

kubectl patch deployment k8s-image-availability-exporter -p '{"spec": {"template":{"metadata":{"annotations":{"prometheus.io/scrape":"true","prometheus.io/port":"8080" }}}} }'
