[CI environment] Added new dependencies and updated pls resources references

[ahmadabdalla]

closes #1803

Description

Private Link services rely on dependences that don't allow it to be successfully deployed. Two issues:

• The Azure Load Balancer frontend cannot be referenced from the existing 'internal' dependency load balancer due to NAT rules. Hence created a new PLS load balancer with 2 separate frontends as we cannot create additional frontends with the existing one.
• The subnets do require private link network policies to be disabled. Hence created new subnets for it.
