What type of PR is this?

Bug

What this PR does/ why we need it:

Bumping to TFA >3.0.0 caused below error in YAKCL https://github.com/mesosphere/yakcl/pull/438

auth/templates/hooks.yaml failed: Job.batch \"traefik-forward-auth-kommander-kubeaddons-session-key-pre-install\" is invalid: spec.template.labels: Invalid value: \"traefik-forward-auth-kommander-kubeaddons-session-key-pre-install\": must be no more than 63 characters"}

I did not find any examples of using generateName in our charts and an upstream issue helm/helm#3348 so decided to go with the safer route and just shorten the name to something that will be <=63 characters

traefik-forward-auth-kommander-kubeaddons-sess-key-pre-install
traefik-forward-auth-kommander-kubeaddons-sess-key-post-delete
