Add support for prowlarr

[Rahulsharma0810]

prowlarr is a better alternative compared with jackett. https://hub.docker.com/r/linuxserver/prowlarr have already identical configuration container image.

this sounds interesting @Rahulsharma0810, did you have the chance to test it in your environment?

[Rahulsharma0810]

not from k8s manifests however from their docker command references working fine.

I've implemented this. It was rather simple:

Add this to your values.yaml

...
prowlarr:
  enabled: true
  container: 
    nodeSelector: {}
    port: 9696
    image_tag: develop
  service:
    type: ClusterIP
    port: 9696
    nodePort: 
    extraLBService: true
  ingress:
    enabled: true
    annotations: {}
    path: /prowlarr
    tls:
      enabled: false
      secretName: ""
  resources: {}
...

prowlarr-resources.yaml

{{ if .Values.prowlarr.enabled }}

I'll add this one and do the config for the custom volume after we're done with #39 and #28

Should be pretty straightforward since @dsfrederic has already done the heavy lifting
