Description

When Auth v2 is enabled, PowerStore secrets provide an endpoint as https://localhost:9400.
Previously, the regex only supported IP addresses, which prevented using localhost or domain-based endpoints.

This change updates the regex validation to accept:

• localhost
• Domain names
• IP addresses (still supported)

This ensures compatibility with Auth v2 configurations and improves flexibility for different endpoint setups.
