Bug Description

After l3 rpc BP got in, we can use RPC to call quantum server instead of quantum client:
class MetadataProxyHandler(object):
    OPTS = [
        cfg.StrOpt('admin_user'),
        cfg.StrOpt('admin_password'),
        cfg.StrOpt('admin_tenant_name'),
        cfg.StrOpt('auth_url'),
        cfg.StrOpt('auth_strategy', default='keystone'),
        cfg.StrOpt('auth_region'),
        cfg.StrOpt('nova_metadata_ip', default='127.0.0.1',
                   help="IP address used by Nova metadata server."),
        cfg.IntOpt('nova_metadata_port',
                   default=8775,
                   help="TCP Port used by Nova metadata server."),
        cfg.StrOpt('metadata_proxy_shared_secret',
                   default='',
                   help='Shared secret to sign instance-id request')
    ]

    Use RPC instead of neutron client in metadata agent

    RPC is a standard way of interacting between Neutron server and agents
    Using neutron client is also inefficient as it results in unneeded
    keystone load and may become a bottleneck at scale

    DocImpact
    When upgrading, one should upgrade neutron server first,
    then metadata agent. However there is a fallback in case
    metadata agent fails to get info from server by rpc -
    it will return to using neutron client.
