Improve migration of external VMware VMs into KVM cluster (#8815)
* Create/Export OVA file of the VM on external vCenter host, to temporary conversion location (NFS)

* Fixed ova issue on untar/extract ovf from ova file
"tar -xf" cmd on ova fails with "ovf: Not found in archive" while extracting ovf file

* Updated VMware to KVM instance migration using OVA

* Refactoring and cleanup

* test fixes

* Consider zone wide pools in the destination cluster for instance conversion

* Remove local storage pool support as temporary conversion location
- OVA export not possible as the pool is not accessible outside host, NFS pools are supported.

* cleanup unused code

* some improvements, and refactoring

* import nic unit tests

* vmware guru unit tests

* Separate clone VM and create template file for VMware migration
- Export OVA (of the cloned VM) to the conversion location takes time.
- Do any validations with cloned VM before creating the template (and fail early).
- Updated unit tests.

* Check conversion support on host before clone vm / create template on vmware (and fail early)

* minor code improvements

* Auto select the host with instance conversion capability

* Skip instance conversion supported response param for non-KVM hosts

* Show supported conversion hosts in the UI

* Skip persistence map update if network doesn't exist

* Added support to export OVA from KVM host, through ovftool (when installed in KVM host)

* Updated importvm api param 'usemsforovaexport' to 'forcemstodownloadvmfiles', to be generic

* Updated hardcoded UI messages with message labels

* Updated UI to support importvm api param - forcemstodownloadvmfiles

* Improved instance conversion support checks on ubuntu hosts, and for windows guest vms

* Use OVF template (VM disks and spec files) for instance conversion from VMware, instead of OVA file
 - this would further increase the migration performance (as it reduces the time for OVA preparation / archiving of the VM files into a single file)

* OVF export tool parallel threads code improvements

* Updated 'convert.vmware.instance.to.kvm.timeout' config default value to 3 hrs

* Config values check & code improvements

* Updated import log, with time taken and vm details

* Support for parallel downloads of VMware VM disk files while exporting OVF from MS, and other changes below.
- Skip clone for powered off VMs
- Fixes to support standalone host (with its default datacenter)
- Some code improvements

* rebase fixes

* rebase fixes

* minor improvement

* code improvements - threads configuration, and api parameter changes to import vm files

* typo fix in error msg
