(#36) Provide certs to Cockroach DB and Zitadel with ExternalSecrets

This patch switches CockroachDB to use certs provided by ExternalSecrets
instead of managing Certificate resources in-cluster from the upstream
helm chart.

This paves the way for multi-cluster replication by moving certificates
outside of the lifecycle of the workload cluster cockroach db operates
within.

Closes: #36
