Use Python 2.6.x compatible syntax for dict comprehension

The dict comprehension syntax used here was added in 2.7.
With minimal change it can be adjusted for Python 2.6.x

Check server terminations on "delete server" tests

Current "delete server" tests check the API response code only
and do not check server terminations. In current tests, Tempest
cannot detect the termination errors even if they happen.
This patch adds the checks for these tests.

Use pretty tox with the ``all`` env

The all entry is usable for running custom set of test
cases selected by a regexp in similar venv
as the gate uses with tox -eall.

The pretty tox helps you to see some basic results before,
 the test suite finished.

unskip test_security_group_rules_negative tests

Neutron validates the uuid format as nova the integer format,
 so if we want 404 for non existent, resource we need to use a valid uuid.

Cleanup _interface class variables in compute/v3

We've already removed xml interface from Nova V3 APIs. So we can assume
the default is json. This commit sets _interface = 'json' to
BaseV3ComputeTest class and removes redundancy.

Remove unused _parse_array functions

They are not used in the current code. So they should be removed.
