Enable running tests via testr

This also disables the functional tests from running. The code is still
left here for posterity. These are intended to be moved into tempest
test cases and thus will be removed entirely at that time.

Use testr for running gate tests

Fixes bug 1172468

Change-Id: Ifd87e44d752b4b3c77b4ea8f38feceb03bccaebe
Remove examples and update testing-overview.txt

With the migration to testrepository, many of the instructions are
obsolete. Also the examples are not needed as we have plenty of fine
examples available in the code itself.

Remove functional tests in preferece for tempest

These tests are not unit tests, and take a long time. They are being
moved into tempest, which is where integration/functional tests live in
OpenStack.

Removing all prints and capturing logging

A new base class for tests is used to reduce repetitive steps used in
a majority of tests. This new base class also uses fixtures.FakeLogger
to suppress logging, though it will be shown on any failures to aid in
debugging the failure.

Prints that happen on normal operation of the test suite are all removed
as they are not needed and only clutter the output.

Remove use of nose attrib plugin and most unittest

Some simple cases that do not use mox still use unittest directly.
Replacing unittest.TestCase with HeatTestCase has the added benefit of
capturing all logging for reporting during failure.

Remove broken --doctest call from run_pep8.sh

It does not seem to actually be required and causes the script to fail
when not running inside tox.

Change-Id: Ib5be301054b08623ea31a97c1b2d6c341e7fdd3e
Re-work run_tests.sh to call testr instead of nose

Running testr directly or running the tests in tox are the preferred
method at this point, but developers may still have automation around
run_tests.sh.

Remove unused and outdated heat/testing dir

The descriptions of testing are not in line with the test suite as it is
today, and none of the code there is actually used.

Change-Id: I717015184fea53d40fc8bd6782dcf4eb8a8520d4
Remove unused skip_unless and skip_test decorators
