Fix resize tests
If we run two resize tests one by one with the same
instance for two resize operations than we have a bug.
First test case test_resize_server_from_manual_to_auto
resizes the instance from flavor_ref to flavor_ref_alt.
After that we reuse this instance for the next test case
test_resize_server_from_auto_to_manual. In this test case
we try to resize this instance from flavor_ref_alt to flavor_ref.
And it causes error "Can't resize disk down".
In this patch we use a new server for each test case.
Firstly we create a new instance, than we set necessary
disk_config and try to resize this instance. Also we added
server_id as parameter for _update_server_with_disk_config()
to set disk_config for specified instance.
