Teleport charts don't play well with ArgoCD

[hugoShaka]

ArgoCD does not implement Helm hooks properly. We got bit several times by this.
The last occurrence was today when a customer's ArgoCD instance deployed the cleanup hook which caused

Workaround:

• add a value to disable every hook in each chart values: this might be usefulful for people using kustomize or helm template

Short term:

• test manually our chart agianst ArgoCD (both latest, and <2.10 as post delete hook implem is different)
• experiment to see if we can detect argo and disable hooks
• experiment and document which argo version deploy which hooks
• add argo hook annotations to our hook resources to either skip them, or have argo do proper thing instead of random harmful stuff
• document this Helm hook horror story somewhere in the charts README so if we were to add new hooks, we know what to do

Mid term:

• create ArgoCD testing instructions (in the Makefile? test plan?)

Long term:

• setup an ArgoCD soaking cluster to detect those issues before users hit them?
