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.

Without this patch, openstackclient has no way to specify to which
project a network belongs upon creation. Instead, it uses the project
ID that the user is authenticating with to fill the tenant_id column.
This is a problem because an admin user is unable to specify a project
for a non-admin network. To fix this and to improve feature parity with
the neutron client, this patch adds project and domain parameters to
the network create command and uses the given project name to look up
the project ID.

Neutron does not allow the project to be changed after creation, so no
such parameter has been added to the neutron set command.

Neutron calls the field 'tenant_id', but this change exposes the
parameter as '--project' to support the newer terminology.

If no project is specified, the client defaults to the previous
behavior of using the auth project.

The v2 catalog list was only printing the last endpoint in
the catalog.
