Description of problem:

neutron.get_floatingip method does not exists, thus when there is a conflict assigning the floating ip, the checking to see if the FIP is already properly assigned will throw exceptions
Version-Release number of selected component (if applicable):


How reproducible:
It always happens when I run automation test in kuryr-tempest-plugin test_port_pool_update under test/scenario/test_port_pool.py

Steps to Reproduce:
1. Run the test
2. Check logs
3.

Actual results:
The test fails with the log provided

Expected results:
Test should pass
