non-empty.  Set a default value of the given name.

This adds a new option --os-cloud that allows the configuration values
for multiple clouds to be stored in a local file and selected with
a single option.

Internal option names have had 'os_' removed to be comptible with
the options returned from OpenStackConfig().get_one_cloud().

The config file is ~/.config/openstack/clouds.yaml:

Sample
------
clouds:
  devstack:
    auth:
      auth_url: http://192.168.122.10:35357/
      project_name: demo
      username: demo
      password: 0penstack
    region_name: RegionOne
  devstack:
     auth:
       auth_url: http://192.168.122.10:35357/

So we really weren't deferring the loading of client libs dadgummit,
do that for real where possible.  This shaves a couple of tenths off
the static import times.

Also defer as much import-time procesing as possible.  This is a little
ugly in api.auth but this also eliminates import of the auth plugins
until they are needed.

Subclass keystoneclient.session.Session to add the timing hooks to
record the elapsed time returned by requests.Response objects, including
the redirection history.  Redirects are included individually and not
rolled into the total time for the original request.

This works for all clients that use OSC's session.

The federation APIs for the identity providers introduce a new parameter
for every identity provider, named remote_ids, which contains a list of
entity ID associated with. This parameter can be provided during the creation
of the identity provider and can be updated at any time. For more information
look at the blueprint:

https://blueprints.launchpad.net/keystone/+spec/idp-id-registration

This patch add the support to this new parameter in the command line by
inserting the option "--remote-id" in the following commands:

- "identity provider create"
- "identity provider set"

Additionally, the values can be read from a file, specified by
"--remote-id-file", containing an entity id per line.
