Helm chart updates related to Prometheus, Webhook HPA, and Flyteconsole probes

[mhotan]

Why are the changes needed?

Various Helm chart updates deemed appropriate to upstream from Union internal usage.

• Add flyteconsole livenessProbe and readinesProbe to mitigate downtime during releases or updates. Default to no probes to preserve backward-compatible behavior.
• Add flyte-console prometheus port and service monitor
• Add flyte-pod-webhook HPA
• Add Prometheus annotations to propeller, webhook, and syncresources

How was this patch tested?

All three patches (commits) were tested individually within Union internal flyte deployment
