Description of problem:
Random scenario tempest tests fail due to 'connection to Floating IP timeout'.
- Connection to the via SSH timed out (see 'test_snapshot_pattern' in 'opendaylight_osp13_flapping_fip.html' attachment)
- Timed out waiting for to become reachable (see 'test_server_connectivity_stop_start' in 'opendaylight_osp13_flapping_fip.html' attachment)
- other relating to not being able to ssh connect to FIP (while VM already has received fixed IP)

Version-Release number of selected component (if applicable):
osp13, puddle 2018-04-19.2

How reproducible:
10%, can be reproduced only if multiple scenario tempest tests are run at the same time (even in serial, concurrenty=1, mode)

Steps to Reproduce:
1. deploy OSP with opendaylight
2. run tempest with --regex tempest.scenario.*

Actual results:
random scenario tempest tests fail to connect to floating IP of VMs

Expected results:
connectivity to FIP of VMs work, tests to pass
