Fix resource_setup order in scenarios

As resource_setup() document says, we should check skip condition before
resource_setup. However some functions in scenarios setup resources
before skip checks. We should avoid to setup unnecessary resources as
possible. This commit fixes the order.

Remove "Disabled Reason" from test_cinder_service_list

The CLI test test_cinder_service_list checks the output of
"cinder service-list" for a set of column titles. One of the titles
it expects to find is "Disabled Reason". However, this title is not
guaranteed to be in the output; cinderclient only appends it if
the value shows up in the response from the server.

Creating individual resources for vpnaas test case

As per design there is only one vpn-service object per router.
Tempest test cases were failing due to creation of multiple
vpn service object for the same single router by raising an
router in use execption.so creating individual resources for
each test cases.

Fix empty string as id in create flavor request

test_get_flavor_details_for_deleted_flavor specify "" as the
id value for creating the flavor.

Nova V2 API validation is loose and the API accepts this
value. However, V2.1 API will not allow empty string as id.

This patch fix this by passing 'None' as id in this test.

Use addCleanup when running swift scenario tests

Helper methods that create containers or objects are now responsible
for providing insurance that the container and object are removed.
delete_wrapper is used so that test cases may choose to delete objects
themselves and the resulting failure to cleanup in addCleanup will
not be an error.

Because deletion is a reasonable "basic op" scenario, the deletion
tests in test_swift_basic_ops are updated so they explicitly
validate deletion while also using addCleanup as a safety measure in
the event the test has unexpected failures.

Add internal methods for setting compute clients

If disabling XML tests on compute API tests by the config item
"xml_api_v2", we need to switch XML clients to JSON clients on
the other project API tests. But current code is difficult to
switch, because compute clients are many and the order is mess.
This patch adds internal methods to set compute clients for
cleanup.
