Switch to using stevedore now so that when the cache implementation is
released all cliff applications can take advantage of the performance
benefits.

After [1] and [2], there is no need to cap the version of cmd2.

This will also fix the current "rally_openstack" import problems
experienced in the CI: http://paste.openstack.org/show/794701/

The mock third party library was needed for mock support in py2
runtimes. Since we now only support py36 and later, we don't need it
in lower-constraints and requirements.

These changes will help us to drop `mock` from openstack/requirements

osc-lib adds support for named groups of commands. There's nothing
particularly openstackclient about this support, so add it here.
This way when we add defered plugin loading, it'll work.

The __future__ module [1] was used in this context to ensure compatibility
between python 2 and python 3.

We previously dropped the support of python 2.7 [2] and now we only support
python 3 so we don't need to continue to use this module and the imports
listed below.

Imports commonly used and their related PEPs:
- `division` is related to PEP 238 [3]
- `print_function` is related to PEP 3105 [4]
- `unicode_literals` is related to PEP 3112 [5]
- `with_statement` is related to PEP 343 [6]
- `absolute_import` is related to PEP 328 [7]

Switch to openstackdocstheme 2.2.1 version. Using
this version will allow especially:
* Linking from HTML to PDF document
* Allow parallel building of documents
* Fix some rendering problems

Update Sphinx version as well.

Disable openstackdocs_auto_name to use 'project' variable as name.

Change pygments_style to 'native' since old theme version always used
'native' and the theme now respects the setting and using 'sphinx' can
lead to some strange rendering.

openstackdocstheme renames some variables, so follow the renames
before the next release removes them. A couple of variables are also
not needed anymore, remove them.

cliff is used by stestr which is used by more things than just
openstack projects - one of them being zuul which still supports
python 3.5. Let's keep supporting 3.5 here for now.

Cliff provides an additional conflict handler for argparse - 'ignore'.
To make this work it subclasses the argparse argument container classes
and adds a handle_conflict_ignore method. It also overrides the group
creation methods to return a subclassed argument group or mutually
exclusive argument group objects. This works, until you add a nested
argument group, at which point a standard argument group object is
returned which does not support the ignore conflict handler.

This change fixes the issue by returning subclassed group objects for
nested groups.

--column='ID:Name'
--column='ID,Name'

This only affects interactive mode.

The desire is to enable a behaviour similar to the shell's set +errexit.
To do this required changing function returns in a number of places in
order to propogate the exit code back up to the app.
