Christian Manivong c8e472b4c6 feat: NAPALM drivers for VMware ESXi and vCenter
Two drivers from one package, both in the hypervisor role:

- vmware_esxi talks to one host directly: facts, vmnics and vmkernel
  NICs, CDP/LLDP neighbours, sensors, VMs, datastores and port groups.
- vmware_vcenter talks to a vCenter: every VM of every host it manages,
  with the host as the VM's node, plus distributed port groups. It
  reports no interfaces of its own; the hosts' NICs belong to the hosts.

Both implement the HypervisorDriver VM contract: get_vms, get_vm_config,
start/stop/reboot/suspend_vm and the four snapshot methods, and emit raw
device warnings (maintenance mode, disconnected host, config issues,
host managed by a vCenter, free license making the API read-only).

Every read is a PropertyCollector query for the explicit paths in
paths.py, converted by to_plain() into dicts and lists; the parsers
only ever see that. tools/harvest.py dumps exactly those paths to JSON
and tools/sanitize.py scrubs the dump, so a real host can become a test
fixture without code changes. A VM's vmid is its instance UUID, which
survives vMotion and re-registration; a MoRef does not.

Tested against govmomi's vcsim in ESXi and vCenter mode, including real
power and snapshot tasks. Not yet tested against real hardware.

"""Shared fixtures: harvested inventories and a fake Inventory that serves them.
The JSON files under ``fixtures/`` were produced by ``tools/harvest.py``
against govmomi's vcsim simulator (``vmware/vcsim`` and ``vmware/vcsim -esx``).
They have the real vSphere shapes but simulator values: vcsim labels devices
``disk-202-0`` where a real host says ``Hard disk 1``, reports no sensors to
speak of, and sets ``managementServerIp`` to ``0.0.0.0``. Tests that need a
branch vcsim does not produce copy a fixture and edit it.
