Salvatore Orlando 9c0fc8e981 Add DB mappings with NSX logical routers
This patch introduces DB mappings between neutron and NSX router,
thus not requiring anymore the Neutron router ID to be equal to the
NSX one.

This change is needed for enabling asynchronous operations in
the NSX plugin.

This patch also performs NVP/NSX renaming where appropriate, and
fixes delete router logic causing a 500 HTTP error to be returned
when a Neutron internal error occurs.

nvp-plugin
-----------------------------------------------------------------------------

Overview and pre-requisites

    This is a Neutron plugin that can talk to a set of NVP controllers and
    implements the core Neutron v2 api.  In order to use it you must have
    Nicira NVP running and configured.  You must also have Neutron installed
    and configured.

NVP Plugin configuration

    1) Database configuration
    The NVP plugin leverages the Neutron database. The following connection
    parameters should be specified:
    - connection: Database connection string
    - max_retries: Maximum number of connection attempts (default 10)
    - retry_interval: Gap between connection attempts (default 2 seconds)
    2) NVP (general)
    - max_lp_per_bridged_ls: Maximum number of ports of a logical switch on a
    bridged transport zone (default 5000)
    - concurrent_connections: Number of connects to each controller node
    (default 10)
    - nvp_gen_timout: Number of seconds a generation id should be valid for
    (default -1 meaning do not time out)
    3) NVP cluster
    By default the Neutron NVP plugin can talk to multiple controllers in a
    single cluster.
    The following parameters can be configured:
    - default_tz_uuid: This is uuid of the default NVP Transport zone that
      will be used for creating tunneled isolated "Neutron" networks. It
      needs to be created in NVP before starting Neutron with the nvp plugin.
    - nvp_controllers: describes the list of controllers
    More details can be found in etc/neutron/plugins/nicira/nvp.ini

Neutron Configuration

    Modify your Neutron configuration for using the NVP Plugin:

    core_plugin = neutron.plugins.nicira.NeutronPlugin.NvpPluginV2
