Fixes #785

  • Support setting the pooler.spec.pgbouncer TLS configuration fields.
  • Support setting the pooler.serviceTemplate field to override the Service configuration for the pooler.

Combining these options allows the chart to deploy a Pooler with a LoadBalancer service, using a TLS certificate that will be valid for clients connecting from outside of the kubernetes cluster.

Example:

poolers:
  - name: external
    type: rw
    poolMode: session
    instances: 1
    clientTLSSecret:
      name: letsencrypt-testdb
    serviceTemplate:
      spec:
        type: LoadBalancer
        loadBalancerIP: .........

The other client/service TLS/CA secret fields are added to the template for completeness.

To be able to configure the pgbouncer spec
with these fields, pass them through from
the values to the templated spec, if provided.
