make neutron-ns-metadata-proxy configurable

Introduced a new configuration parameter for DHCP and L3 agent
to be able to set the path of the metadata socket to be used
by neutron-ns-metadata-proxy when started inside the DHCP or L3
agent. Also moved the configuration parameter of the
neutron-ns-metadata-proxy to the CLI parameters.

refactor port binding codes

Bug #1195047

This patch:
1. removes the iteration in get_ports to call extend_dict_binding
2. uses a unified way for plugins to do this kind of stuff

ml2 will enhance the binding so that it can have different binding
for port according to port's host.
mlnx and bigswitch are also exceptions due to the dynamic binding info.

Make DbPlugin accept status in create_network().

This commit makes NeutronDbPluginV2 get network status from input at
create_network() to allow other plugins to set network status while
creating DB entry.

Now plugins can create network with any status in a single DB commit.
(e.g. Set network status to 'DOWN' when admin_state_up is False.)

This commit also changes NeutronDbPluginV2TestCase() to make default
network status configurable in each plugin test case.

Do not alter test_config global in test_extension_ext_gw_mode

Bug 1199557

Instead, allow subclasses to instruct the base test class which
API extension manager they should use as it is already done with
the plugin name.
