fix: (IAC-645) Updated CAS transformer templates for CAS workers and backup

[riragh]

Changes:

CAS transformers for workers and backup used for default CAS (provider's) are targeting "All" CASDeployments. For MT deployment, the values in the provider's CAS transformers overwrite the values for tenants' CAS during kustomization ignoring the user specified values for tenants' CAS.
The stale files cas-manage-workers.yaml and cas-manage-backup.yaml were updated to use latest CAS changes.

Tests:

Deployments were successful for all the scenarios with expected number of workers and backup controllers. See internal ticket for details.

• Multi-tenant MPP deployment with 2 workers and backup controller -> Onboard ACME tenant with 1 worker and 0 backup controller
• (Extended scenario1) Multi-tenant MPP deployment with 2 workers and 1 backup controller -> Onboard ACME tenant with 1 worker and 0 backup controller --> onboard another tenant INTECH with 0 worker and 1 backup controller
• Multi-tenant MPP deployment with 2 workers and backup controller -> Onboard ACME tenant with 2 worker and 1 backup controller
• Non Multi-tenant MPP deployment with 3 workers and 1 backup controller

Talked with Ritika about these changes. The contents are from the product team. Updated these files so that we are sync'ed with their latest and it works on MT and non-MT.
