Resources for init container not specified into helpers/_pods.tpl

[zippo761]

Checks

• I have checked for existing issues.
• This report is about the User-Community Airflow Helm Chart.

Motivation

In my compary use strong rules into k8s production cluster that resource quota must be specified for every container. So every deploy without resources into init-containers i catch WARNING like this for every pods (that contain init-container/check-db/wait-for-db-migrations/install-pip-packages:

Implementation

Im propose specified resource into template charts/airflow/templates/_helpers/pods.tpl and fill values for template
somethink like this:

.Values.airflow.

# resource for check-db init container
checkDb:
  resources: {}

# resource for wait-for-db-migrations container
waitForDbMigrations:
  resources: {}

# resource for install-pip-packages container
installPipPackages:
  resources: {} 

and users after this update use only values for avoid this warning
