Introduce load_tests mechanism for negative tests

The test loader will run the function given in the local variable
"load_test" (see http://docs.python.org/2/library/unittest.html#load-tests-protocol).
This is done after the import level and only if a valid test runner is
in place. Therefore it will solve the issue with pep8 job since
flake8 won't interpret the load_tests variable.

Validate get keypair attributes of Nova V2/V3 API

This patch adds the JSON Schema for response of Nova V2 & V3 GET
keypair API and validate the response with added JSON Schema to

Renew token before expiry time

Modify is_expired so that token is renewed before it
actually expires. The threshold is set to 60s, which is plenty
of time for any API call to complete.
Use utcnow() instead of utc(). Includes unit tests for is_expired.

Closes bug 1292145

Fail a test if stack delete failed

Whenever a deleting stack goes to DELETE_FAILED this is an error which should fail
the test. Currently delete failures are ignored. As a side-effect of this, delete-failed
stacks are leaked even though tests pass.

The test may have done is own assertions on stack deletes, so a NotFound
exception is still passed.
