Helm chart doesn't trigger config reload

[jbergler]

Describe the bug
When changes are made to just the hajimari config in the help chart, eg turning showAppUrls off the container does not pick up the config change automatically

To Reproduce
Steps to reproduce the behavior:

1. Deploy helm chart
2. Make a change to showAppUrls in values.yaml
3. Wait until chart is deployed (via flux)
4. Refresh hajimari, config is not updated
5. Delete pod, and let it restart
6. Config is updated

Expected behavior
Changing the config should either restart the pod or otherwise trigger a reload of the config.

@toboshii could you please review above PR? This bug is a bit annoying.

It's also possible to solve the issue using third-party updaters, e.g. stakater/reloader.

After installing it, Hajimari chart's values need to be populated with following block:

controller:
  annotations:
    configmap.reloader.stakater.com/reload: "hajimari-settings"

But I'm looking forward for PR above to be merged as more suitable solution 👍
