Merge shade and os-client-config into the tree
This sucks in the git history for both projects, then moves their files
in place. It should not introduce any behavior changes to any of the
existing openstacksdk code, nor to openstack.config and openstack.cloud
- other than the name change.

TODO(shade) comments have been left indicating places where further
integration work should be done.

It should not be assumed that these are the final places for either to
live. This is just about getting them in-tree so we can work with them.

The enforcer code for reasons surpassing understanding does not work
with python setup.py build_sphinx but it does work with sphinx-build
(what?) For now turn it off. We can turn it back on once the build
sphinx job is migrated to the new PTI.

openstacksdk Style Commandments

Read the OpenStack Style Commandments http://docs.openstack.org/developer/hacking/

Indentation

PEP-8 allows for 'visual' indentation. Do not use it. Visual indentation looks like this:

return_value = self.some_method(arg1, arg1,
                                arg3, arg4)

Visual indentation makes refactoring the code base unneccesarily hard.

Instead of visual indentation, use this:

return_value = self.some_method(
    arg1, arg1, arg3, arg4)

That way, if some_method ever needs to be renamed, the only line that needs to be touched is the line with some_method. Additionaly, if you need to line break at the top of a block, please indent the continuation line an additional 4 spaces, like this:

for val in self.some_method(
        arg1, arg1, arg3, arg4):
    self.do_something_awesome()

Neither of these are 'mandated' by PEP-8. However, they are prevailing styles within this code base.

Unit Tests

Unit tests should be virtually instant. If a unit test takes more than 1 second to run, it is a bad unit test. Honestly, 1 second is too slow.

All unit test classes should subclass openstack.tests.unit.base.BaseTestCase. The base TestCase class takes care of properly creating OpenStackCloud objects in a way that protects against local environment.
