Enable remote debugger in nova

[Tracy Jones]

This is really not a bug but a feature

Glance and Keystone both support the use of a remote debugger. It would be nice to add that to nova as well.

    Enable remote debugging for nova

    This patch added 2 command line parameters which are used to
    connect to an external debugger such as pycharm or eclipse.
    This feature is used when you want to connect to a nova
    service via a debugger running on a different host.
    To use it you start the nova service with the following
    command line parameters

    --remote_debug-host <where the debugger is running>
    --remote_debug-port <port> it's listening on>.
