Constructor create vmware connector to vCloud director.

a) It initialize organization UUID
b) Initialize tenant_id/vdc ID. (This information derived from tenant name)
Args:
uuid - is organization uuid.
name - is organization name that must be presented in vCloud director.
tenant_id - is VDC uuid it must be presented in vCloud director
tenant_name - is VDC name.
url - is hostname or ip address of vCloud director
url_admin - same as above.
user - is user that administrator for organization. Caller must make sure that
username has right privileges.
password - is password for a user.
VMware connector also requires PVDC administrative privileges and separate account.

'permissions': (optional) string with file permissions, typically octal notation '0644'
'owner': (optional) file owner, string with the format 'owner:group'
'boot-data-drive': boolean to indicate if user-data must be passed using a boot drive (hard disk)
'disk_list': (optional) list with additional disks to the VM. Each item is a dict with:
'image_id': (optional). VIM id of an existing image. If not provided an empty disk must be mounted
'size': (mandatory) string with the size of the disk in GB
availability_zone_index: Index of availability_zone_list to use for this this VM. None if not AV required
availability_zone_list: list of availability zones given by user in the VNFD descriptor. Ignore if
availability_zone_index is None
Returns a tuple with the instance identifier and created_items or raises an exception on error
created_items can be None or a dictionary where this method can include key-values that will be passed to
the method delete_vminstance and action_vminstance. Can be used to store created ports, volumes, etc.
Format is vimconnector dependent, but do not use nested dictionaries and a value of None should be the same
as not present.
