Fail a test if time.sleep called for no reason

If a mild error screws something up in task manager, an entire class
of tests will continue polling using GET requests until they hit their
rate limit, destroying any attempt to parse the test output to see
what is wrong. This pull request fixes that.

Get service endpoints from catalog

* Add catalog to TroveContext
* Populate context with catalog in middleware
* No new keystone calls made
* If *_url from conf available, it overrides catalog
* Following clients now use service_catalog:
    * cinder
    * heat
    * nova
    * swift
* Add new conf options (necessary to maintain parity with flexibility
  of *_url in conf):
    * os_region_name
    * cinder_service_type
    * heat_service_type
    * nova_service_type
    * swift_service_type

According to the OpenStack translation policy available at
https://wiki.openstack.org/wiki/LoggingStandards debug messages
should not be translated. Like mentioned in several changes in
Nova by garyk this is to help prioritize log translation.

Consider datastore version when generating configs

This commit upgrades the bit of code which determines the datastore
config to render. Currently that code only acknowledges the datastore
manager, but with this config it's possible (but not required) to let
it use a unique config based on version or even flavor.

Remove all mostly untranslated PO files

We only import PO files that are at least 75 % translated,
so we can delete now all other PO files. The patch only
removes the mostly untranslated files. Once a file becomes mostly
translated, the bot will import it again.

This removes all languages besides en_US.

Cleans up ServiceUser.__str__ method

Reasons:
- ServiceUser.__str__ in trove/tests/util/users.py contains code
  after the return statement.
- This code after unconditional return statement has no use.
- Thus, ServiceUser.__str__ method needs cleanup.

Changes:
- Removes the statements after return statement.
- Adds tenant name to the __str__.

Remove admin_token from configs

A previous review removed the admin_token from the sample config file.
It appears that devstack doesn't use that file but instead uses one of
the .test files.

Admin tokens are actively discouraged as a form of authenticating in
auth_token middleware and the behaviour when using admin_token in
combination with a username and password (as this default produces in
devstack) can lead to problems in authentication.
