Description of problem:
Running 
openstack loadbalancer pool create --help 
returns
--protocol {TCP,HTTP,HTTPS,TERMINATED_HTTPS,PROXY,PROXYV2,UDP,SCTP}

even though TERMINATED_HTTPS is not a supported pool protocol.


The Octavia API denies the call when one tries to create a TERMINATED_HTTPS pool:

(overcloud) [stack@undercloud-0 ~]$ openstack loadbalancer pool create --name pool1 --lb-algorithm ROUND_ROBIN --listener listener_h2 --protocol TERMINATED_HTTPS
Invalid input for field/attribute protocol. Value: 'TERMINATED_HTTPS'. Value should be one of: TCP, PROXY, SCTP, HTTP, HTTPS, UDP, PROXYV2 (HTTP 400) (Request-ID: req-baaf8d0d-2881-4ca6-b83b-80bbe6f4f3cd)


Version-Release number of selected component (if applicable):
(overcloud) [stack@undercloud-0 ~]$ cat core_puddle_version                                                                                                   
RHOS-17.1-RHEL-9-20220830.n.1

How reproducible:
100%

Steps to Reproduce:
1. Deploy Octavia
2. Run openstack loadbalancer pool create --help

Actual results:
TERMINATED_HTTPS appears as a valid option for pools.

Expected results:
TERMINATED_HTTPS should not appear as a valid option for pools.
