Automatically add Application labels

[deefdragon]

It would be really useful for management reasons to have the helm chart automatically add the necessary labels to all the lago deployments/jobs be grouped into one application.

Specifically, I use Kontena Lens, and their top level Application overview automatically groups things together based on these labels, which is great for making sure that everything is working & addressing everything all in one place.

I tried adding the necessary labels manually, but unfortunately, the podLabels section does not apply labels to the assorted deployments, only to the pods.
