the existing one.

Version-Release number of selected component (if applicable):

How reproducible:
Deploy OSP 13 upgrade octavia to OSP16. Notice the admission controller is not removed. 

Steps to Reproduce:

Comment 3 Jon Uriarte 2020-04-03 10:45:00 UTC
Verified in 4.5.0-0.nightly-2020-04-02-115550 on top of OSP 13 2020-03-25.1 puddle.

Upgrading the OSP octavia from 13 to 16 is detected by the cno and acts accordingly,
the admission controller pods are removed as it supports double listeners with the new
octavia version and the amphora driver.
