Tempest gate fails due to missing library

[Shachar Snapiri]

Tempest gate fails due to a missing dependency library - neutron-tempest-plugin.
Tests fail as follows:
Failed to import test module: neutron_dynamic_routing.tests.tempest.api.test_bgp_speaker_extensions Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/unittest2/loader.py", line 456, in _find_test_path module = self._get_module_from_name(name) File "/usr/local/lib/python2.7/dist-packages/unittest2/loader.py", line 395, in _get_module_from_name __import__(name) File "/opt/stack/new/neutron-dynamic-routing/neutron_dynamic_routing/tests/tempest/api/test_bgp_speaker_extensions.py", line 21, in <module> from neutron_tempest_plugin.api import base ImportError: No module named neutron_tempest_plugin.api

    Add neutron_tempest_plugin to tempest dependencies

    This is required for the bgp tests to succeed.
    Without it, tests fail as follows:
    Failed to import test module: neutron_dynamic_routing.tests.tempest.api.test_bgp_speaker_extensions
    Traceback (most recent call last):

From a double commit:

 * https://review.openstack.org/519310 syncs the code from neutron project to neutron-tempest-plugin repo and it is better to depend on new one in order to avoid the breakage.

* https://review.openstack.org/#/c/521346 transforms the bgp tempest tests to use the new repo.
