Chart deployments are missing PDB and HPA for HA #13391
Description
Ideally the pods created by the deployments should be able to:
- Optionally autoscale (using regular HPA)
- Prevent that all pods are evicted at the same time, so at least a minimum number of replicas are up and running when doing a rollout restart or the node starts evicting pods
The chart should allow to optionally create both (probably PDBs should be enabled by default with some safe values?) so out of the box the chart will deploy an HA capable solution.
