CLOUDSTACK-9379: Support nested virtualization at VM level on VMware Hypervisor## Introduction

[JIRA TICKET](https://issues.apache.org/jira/browse/CLOUDSTACK-9379)

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.

A new global configuration is added, to enable/disable VM nested virtualization control: `'vmware.nested.virtualization.perVM'`.
Default value=false

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 this 3 values:**
- **(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, **(3)** indifferent  -> _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, **(3)** indifferent -> _DISABLED_
