VMware: refactor how we iterate result objects from vCenter

[Radoslav Gerganov]

There is lot of duplicate code which does the following (pseudo code):

result = session.get_objects_from_vcenter()
while result:
    do_something(result)
    token = get_token(result)
    if token:
        result = session.continue_to_get_objects(token)
    else:
        break

The part that retrieves more objects if token is returned is repeated over and over again. We need to come up with a common utility (e.g. an iterator) which abstracts this boilerplate and then have something like:

for result in session.get_objects():
    do_something_with_result(result)
