Add Cadence Internal TLS feature

[CosminL-DEV]

Enhancement to support internal TLS communication between cadence-server pods and cadence-web to frontend.

Something like this added to the schema and configurable in values.yaml.

services:
  frontend:
    rpc:
      tls:
        enabled: true
        certFile: config/credentials/keytest.crt
        keyFile: config/credentials/keytest
        caFiles:
          - config/credentials/client.crt
        requireClientAuth: true

  matching:
    rpc:
      tls:
        enabled: true
        certFile: config/credentials/keytest.crt
        keyFile: config/credentials/keytest

  history:
    rpc:
      tls:
        enabled: true
        certFile: config/credentials/keytest.crt
        keyFile: config/credentials/keytest

clusterGroupMetadata:
  clusterGroup:
    cluster0:
      tls:
        enabled: true
