Story

As an admin of RHDH, I want to be able to configure default mounted secrets

• several secrets (like PVCs)
• per-secret secret's mountPath 
• containers the secret should be mounted to (not only Backstage container)

Background

For the time it is possible to configure only one (multi keys) secret by default with no ability to configure mount path and no ability to mount to other than Backstage container, which is blocker for using default configuration for dynamic-plugins init container (for example).

Dependencies and Blockers

QE impacted work

Documentation impacted work

Acceptance Criteria

• It should enable multi-object configuration (like in PVC) for secret-files.
• It should provide a way to mount some secrets (like dynamic-plugins-npmrc, dynamic-plugins-registry-auth) in the init container only, not the main container.
• It should be documented

upstream documentation updates (design docs, release notes etc)
