Argo Workflow: Postgres SSL Certificate Configurations if SSL is enabled

[reddymh]

Describe the bug

If you enable the ssl & sslmode for persistence then controller and server expects postgres tls certificate path so I have fixed the bug and raised the PR.

Details:

Issue LinK: argoproj/argo-workflows#10234
PR: argoproj/argo-workflows#10300

Related helm chart

argo-workflows

Helm chart version

v3.3.8

To Reproduce

1. enable ssl to true & sslmode to verify-ca or require or verify-full
2. controller and server will fail to start because postgres config expects tls certificates and there is no way to configure postgres SSL certificates.

Error Log:

time="2022-12-14T20:28:04.198Z" level=info msg="SSO enabled"
time="2022-12-14T20:28:04.202Z" level=info msg="Starting Argo Server" instanceID= version=latest+unknown

time="2022-12-14T20:28:04.222Z" level=fatal msg="pq: connection requires a valid client certificate"

Expected behavior

Argo Workflow server and controller should work when I configure postgres DB with ssl and all the modes of ssl.
