Version-Release number of the following components:
OCP 4.4.0-0.nightly-2020-03-01-212047

How reproducible:
every time

Steps to Reproduce:
1. Deploy OSP16 with (not working) octavia
2. Deploy OCP 4.4 on top of openstack
3. Attempt to destroy OCP

Actual results:
Destroy failed

Expected results:
Installer should avoid failing the destroy if octavia has not been used for deployment and octavia is not in working state. Instead warning could be displayed
