Check for host sizing during Cloud Connector installation

If using Cloud Connectors as part of a Citrix DaaS deployment, the Cloud Connector High Availability service allows for the continued brokering of Connections even during network interruption or service outages. However if Cloud Connectors are not correctly sized for outage mode this can cause launch failures.

With this change, the Cloud Connector installer will introduce a warning in cases where the host Windows machine is under-sized for operation in Local Host Cache mode. For cases where the connector is not being used to broker connections (e.g. for AD connectivity) this warning will not block installation.
