Add upgradeGroup data source

Do we know when the upgrade groups are created in NSX config? If they are not yet ready by the time data sources are evaluated, we need a special handing (at least not to fail config)

Thanks. Good one. I didn't find any places mentioning this. I have added a polling func to avoid this issue.

If the groups are not yet populated by NSX at the time config is evaluated, perhaps we better fail fast rather than wait (and also recommend making groups dependant on prepare resource, if that resources triggers group creation.
if we have established that prepare resource triggers groups creation, we may also consider making this dependency explicit by adding a fake attribute prepare_upgrade_id or something similar.

As I tested, upgrade groups will be created after a few seconds after the upgrade bundle upload starts.
Added the attribute for the sake of dependency and change the timeout to 1 min.
