[DEV-15064] Fixes to allow creating on-prem test infra

[NathanOkolita]

Note

Medium Risk
Changes how on-prem test environments provision Postgres/RabbitMQ storage and pgBackRest backups, which can affect data persistence and recovery behavior. Also enables additional operators in on-prem mode, increasing the surface area of infra changes during deploys.

Overview
Improves support for on-prem test deployments by making Postgres storage configurable between local hostPath PVs and NFS-backed dynamic provisioning via new on_prem_volume_backing.

Updates the Crunchy Postgres Helm overrides to support a configurable instance-set name (crunchy_instance_name) and to switch pgBackRest from S3-backed repos to a PVC-backed repo when on_prem_test is enabled.

Hardens the on-prem NFS setup by adding an exports ConfigMap, initializing required subdirectories, updating the NFS server image/pull secrets, and increasing the backing PVC size; additionally wires on-prem defaults so core operators (crunchy-pgo, migrations-operator, rabbitmq-operator, dragonfly-operator) can be enabled for on-prem test runs and sets RabbitMQ persistence to use nfs-client when applicable.

Default instance name changed from pgha2 to pgha1

High Severity

The new crunchy_instance_name variable defaults to "pgha1", but it replaces the previously hardcoded value "pgha2" in the else branch of crunchy_instances_values. This else branch is used for all standard (non-on-prem-local) deployments, including production. Existing deployments that don't explicitly set this variable will see their Crunchy PostgreSQL instance set name change from pgha2 to pgha1, which could trigger the operator to destroy and recreate the StatefulSet, risking data loss or downtime.
