-        Constructor create vmware connector to vCloud director.

-        If client specified username , password and host and VDC name.  Connector initialize other missing attributes.
-
-        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.
