Refactor usage of custom_match tests

For some requests a check outside of custom_match was used, thus
bug #1262534 was not completely closed.

This patch refactors part of the code to use custom_match
as far as possible and also adds some more checks.

Moves negative tests from test_server_metadata

This change set moves the negative tests in
tempest/api/compute/servers/test_server_metadata to
a new file test_server_metadata_negative

Also removes usage of modules directly and qualifies
test_server_create_metadata_key_too_long as negative test.
 ** seprates test into individuals
Note: HACKING.rst
The second requirement is that all negative tests must be added to a negative
test file. If such a file doesn't exist for the particular resource being
tested a new test file should be added

Avoid expiration before updating metadata

The X-Delete-At value might already be in the past after the initial
object creation because the current time is used to set the
X-Delete-At value. Creating the initial object before starting each
test prevents this.

Rewrite RemoteClient.get_boot_time()

This is doing conversion between time formats, while we could really
just stay in seconds. This also fixes the method to work for cirros,
which doesn't know about human readable time formats.

Make --debug flag on run_tests and run_tempest use testtools.run

This commit changes the --debug flag on run_tests.sh and run_tempest.sh
so that instead of setting set +o xtrace will run tests with testools.run.
This enables pdb to work because calling subunit.run or using testr will
interfere with pdb.

Check if service is available for cli tests

This commit adds checks to the CLI tests to see whether the service
that is being tested is available or not. Previously the tests would
run regardless of whether the service was listed as available in the
config file or not.

Fix class inheritance for volume_types tests

Previously the tests in test_volume_types.py manually setup an
admin_client using the admin credentials specified in the config file.
However, this is not correct because with tenant isolation those
credentials shouldn't be used other then to create a new tenant.
Additionally, everything performed in the test class's setUpClass was
already done in the base class. This commit corrects this by
changing the test class inheritance to the proper base class.

tighten up isolated creds create

we're spewing giant user and tenant names in logs, which make
actually getting to the bottom of things less useful, as we're
constantly doing left / right scrolling. Shorten this up.

this changes makes a number of fix ups here.

1) it shortens down the name to just classname + rand piece, no
need to add extra -tempest- -tenant, as it's pretty redundant. We
throw out any value which has a '.' in it, because that's not a
class name.

2) it fixes the scenario isolated creds call. __name__ is package
name, and cls.__name__ actually gives us the class name.

3) it stops using a variable in a different namespace as a
temporary variable for isolated creds create. This looks like it
was based on a find / replace refactor to remove importing modules.
It worked, but it was wrong.

4) it stops using the same random bits for user & tenant. There is
no reason these should match, and in the new scheme they would if
they shared random bits.

Remove super call in overloaded close()

Change Ia30058bc4752489107b998bd44d38c27901cfe63 introduced a super()
call after overloading the close() method in VerifiedHTTPSConnection.
However, the parent class httplib.HTTPConnection was definied using
the old-style class contructor so the super() call won't work. This
commit fixes that by removing the super() call and explicitly calling
the parent class's close() method.
