Add support for PodDisruptionBudgets and topology spread constraints
to enable robust high-availability deployments.
Changes:
- Add PDB templates for api, webhooksServer, and externalWebhooksServer
- Add topologySpreadConstraints to deployment templates
- Add configuration options in values.yaml with sensible defaults
- Update README with new parameter documentation
For HA deployments, users can now:
- Enable PDBs to ensure availability during voluntary disruptions
- Configure topology spread constraints to distribute pods across zones
Example usage:
```yaml
api:
replicas: 2
podDisruptionBudget:
enabled: true
minAvailable: 1
topologySpreadConstraints:
- maxSkew: 1
topologyKey: topology.kubernetes.io/zone
whenUnsatisfiable: ScheduleAnyway
labelSelector:
matchLabels:
app.kubernetes.io/component: api
```

Note that #5396 was not yet evaluated by any maintainers and remains in a proposal state, as indicated by its labels. We can take a look at this, but it's going to receive the scrutiny now that it should have received before anyone spent time implementing it. @hiddeco would you mind having a look at this, but only if you have the bandwidth? |
