[Feature]: Add feature to add additional Containers in the Helm chart

[viktor-ozherelev]

Description

We are deploying nessie to Kubernetes via Helm chart. We use PostgreSQL with SSH connection as the version store type. In order for nessie to have a permanent and isolated connection to the database via an SSH tunnel, we need to run a parallel Container.

I suggest adding an additional container configuration where it can be possible to create parallel processes for nessie.

I am ready to do PR if you share my idea.

Expected Use Cases

Add parrallel SSH tunnel for PostgreSQL jdbc connection

Requested Changes in public API
