Support for VMWare cloud

Requester: jabia (for Image Builder project)

Issue: Add VMWare to the list of supported cloud. Image builder team performs some tests on this cloud and having this option would enable us to use cloudwash

Urgency: Together with #72 and #74, they are must have features for Image Builder to start using cloudwash. In the meantime, the team will continue using cloud-cleaner.

Willing to Contribute: Yes, although the priority is not very high so we might struggle to find the time to do it.

@jabia99 Looks like the title and description differs. Can you focus on need of adding VMWare compute resource in description than negative logic implementation.

@omkarkhatavkar There are 2 more requests made by requester to say this is done.

1. opt in/out support
2. Filter by tag

[jyejare]

We can still check with @ghost though that if he could help us with testing the VMware for which @Gauravtalreja1 was looking for.

The request is mini satisfied by #114
