[Bug 1654283] [NEW] test_router_interface_status raises troublesome error when it fails.

Public bug reported:

Test: neutron.tests.tempest.api.test_routers#test_router_interface_status
This test waits for the router interface port to become active by using neutron.common.utils.wait_until_true.

Problem is when it, for whatever reason, would not become active, this
test raises an exception from eventlet.

This particular error being raised by eventlet (eventlet.timeout.Timeout) isn't a subclass of the Python Exception, but is a subclass of BaseException
And this causes the entire test cycle to hardstop. Even when there are still other tests left to run.


Error Trace:
