When test_server_commands_main_help() fails it dumps a ton of
unformatted text on an exception message. This commit attempts to clean
it up to make it easier to read.

The base job has tox_install_siblings: false - which we want. But
that means we need tox_install_siblings: true on the tips job.

While we're at it - add fetch-tox-output so that we have tox log files
in the fetched build output for easier verification of what wound up
installed.

Don't look for ResourceNotFound string in test

The string ResourceNotFound is not in the error string anymore. Look for
the text that is.

Add support for creating, retrieving, and deleting application
credentials. Application credentials do not support updates.

In order to provide a positive user experience for the `--role` option,
this patch also includes an improvement to the
`identity.common._get_token_resource()` function that allows it to
introspect the roles list within a token. This way there is no need to
make a request to keystone to retrieve a role object, which would fail
most of the time anyway due to keystone's default policy prohibiting
unprivileged users from retrieving roles.

This commit makes to use stestr instead of ostestr
directly. ostestr>1.0.0 has started to use stestr instead of
testrepository. So there is no reason to use ostestr anymore.

At now, OSC command implementation extracts resource attributes based on
a predefined column list, so if a user specifies an unknown attribute
not defined in the column lists, such attribute will be ignored.

In case of 'port list', the neutron port defines many attributes and
it is not a good idea to show all attributes even in the long mode
from the perspective of user experience.

This commit consumes osc_lib.utils.calculate_headers_and_attrs()
function to show undefined port attributes if requested in -c option.

We used that module in a test functional for module list, it is being absorbed
into python-openstacksdk and having it listed in this test breaks -tips jobs.
