ci!: deprecate deployment config, remove image stream - db only

[DerekRoberts]

Replaces deprecated Deployment Configs with Deployments. Also removes image streams and uses a randomly generated envar to ensure consistent rollouts.

Unfortunately there will be some downtime when this deploys.

Steps:

• Delete deployment configs and services for TEST database and backend
• Delete deployment configs and services for PROD database and backend
• Merge this PR
• Let deployments to TEST and PROD complete

Part of #1123.
