[Feature]: Add support for pooled hostpools

[Smalls1652]

What kind of change is this?

Change/Update

What's the description of the change?

Instead of focusing on just personal hostpools, pooled hostpools, which are used for multi-session hosts, should be monitored as well.

What are the proposed changes that need to be made?

• Change the logic for adding hostpools that should be monitored. Specifically removing the check if a hostpool is personal or not.
• Implement a new way for ResourceManager to add hostpools for monitoring.

With the last point, I'm currently using an Azure resource tag defined on the hostpool resources to enable ResourceManager to monitor it. This would be a breaking change.
