Fix test_provider_token_expiration_validation transient failure

The keystone.tests.test_token_provider.TestTokenProvider.
test_provider_token_expiration_validation test would fail if the
tests weren't run before the expiration period passed. This could
happen if the system was slow and the previous tests took a long
time causing a potential transient failure.

Start using to oslotest

oslotest provides a BaseTestCase class then enables proper capturing of
stdout, stderr and logging streams during a test run. We will take
advantage of this capability in the near future.

Use assertIn in test_v3_catalog

assertEqual was used where assertIn should have been. assertIn
will provide a more useful error message.

Cleanup revocation query

The code in the revoke sql backend to calculate the query for the
list of events was creating a temporary and then discarding it,
and blaming not using it on sqlite.

Rather than discard the temporary, a reference is kept to it so
that it can be used.

Allows override of stdout/stderr/log capturing

During a test run stdout, stderr and log messages are being captured. If
the test fails all three will be printed out so that can be inspected.
Each stream has an environment variable that can be used to stop it from
being printed at the end of a test run by setting its value to 0. This
is in line with what many of the other project are already doing.

Environment variables:

 - OS_STDOUT_CAPTURE for stdout
 - OS_STDERR_CAPTURE for stderr
 - OS_LOG_CAPTURE for logging

Use CMS to generate sample tokens

This is preparing for compressed tokens.  We don't want anything in the
keystone server tree that assumes it knows the formats of the token.
This uses the CMS code to preduce the sample data.

code hygiene; use six.text_type, escape regexp's, use key function

Some simple code clean up for code hygiene

Need to use unicode() rather than str() to properly handle non-ascii
characters, but to be PY2/PY3 compatible use six.text_type.

Regexp's were formed by string formatting using run-time substitutions
but the substitutions were not escaped. If the substituion contained
regexp metachars the regexp could fail.

The db key was formed by string substituion but this code was
duplicated in many places, introduce a method, key() to eliminate the
code duplication. At the same time introduce the dn() method to
transform the dn to an internal format. Currently the dn() method is a
place holder whose implementation will be added in a subsequent patch.

Remove unnecessary test setUps

There is no reason to have a setUp case if all we do is chain to the

Avoid using .values() on the indexed columns

The length of a dict-like object should be the same as the length of the
list of values in the object, so calling .values() should be unnecessary
here.
