@jburwell This sounds like a good idea. In this PR all abstraction work is
done so the things to do would be to implement support in respective hypervisor
resources as well as strip "vmware." prefix from conjuration items. @nvazquez
is preparing intragrtion test based on @rhtyd idea

> h2. Introduction
> It is desired to support nested virtualization at VM level for VMware
> hypervisor. Current behaviour supports enabling/desabling global nested
> virtualization by modifying global config {{'vmware.nested.virtualization'}}.
> It is wished to improve this feature, having control at VM level instead of a
> global control only.
> h2. Proposal
> A new global configuration is added, to enable/disable VM nested
> virtualization control: {{'vmware.nested.virtualization.perVM'}}. Default
> value=false
> h2. Behaviour
> After a vm deployment or start command, vm params include
> {{nestedVirtualizationFlag}} key and its value is:
> * true -> nested virtualization enabled
> * false -> nested virtualization disabled
> We will determinate nested virtualization enabled/disabled by examining:
> * (1) global configuration {{'vmware.nested.virtualization'}} value
> * (2) global configuration {{'vmware.nested.virtualization.perVM'}} value
> * (3) {{'nestedVirtualizationFlag'}} value in {{user_vm_details}} if present,
> null if not.
> Using this 3 values, there are different use cases:
> # (1) = TRUE, (2) = TRUE, (3) is null -> ENABLED
> # (1) = TRUE, (2) = TRUE, (3) = TRUE -> ENABLED
> # (1) = TRUE, (2) = TRUE, (3) = FALSE -> DISABLED
> # (1) = TRUE, (2) = FALSE -> ENABLED
> # (1) = FALSE, (2) = TRUE, (3) is null -> DISABLED
> # (1) = FALSE, (2) = TRUE, (3) = TRUE -> ENABLED
> # (1) = FALSE, (2) = TRUE, (3) = FALSE -> DISABLED
> # (1) = FALSE, (2) = FALSE -> DISABLED
