[BZ] The script for certs check fails with Openstack client version 3.18.1

The script for checking the certs for Openshift install on openstack fails. 

https://docs.openshift.com/container-platform/4.12/installing/installing_openstack/preparing-to-install-on-openstack.html#security-osp-validating-certificates_preparing-to-install-on-openstack

I see that the command "openstack catalog list --format json --column Name --column Endpoints" returns output as,

Which then expected to be filtered with jq as " | jq -r '.[] | .Name as $name | .Endpoints[] | [$name, .interface, .url] | join(" ")'| sort " 


But it fails with error as,

----------------
./certs.sh
jq: error (at <stdin>:46): Cannot iterate over string ("RegionOne\...)

Further check the script following commands execution is  failing
 openstack catalog list --format json --column Name --column Endpoints \
> | jq -r '.[] | .Name as $name | .Endpoints[] | [$name, .interface, .url] | join(" ")'
jq: error (at <stdin>:46): Cannot iterate over string ("RegionOne\...)
----------------

Where certs.sh is the script we copied from documentation.

I did some debugs to get the things .interface,.url to internal,public,admin fields from endpoint but I'm not sure if that's way it is on openstack so marking this as BZ to have reviewed.

Openshift Container Platform 4.12 on 3.18.1 release of openstack 

- Always

1. Copy the script and run it on given release of openstack version. 2.
3.

Fails with parsing 

Shouldn't fail.
