Yeah, they do:
[root at centos-distro openstack-ansible]# rpm -qa | egrep "amqp|kombu" 
[root at centos-distro openstack-ansible]#

But not sure about keystoneauth1 since I see this at the point in oslo.messaging. Full error in systemd looks like this:
Jan 30 11:51:04 aio1 nova-conductor[97314]: 2021-01-30 11:51:04.543 97314 ERROR oslo.messaging._drivers.impl_rabbit [req-61609624-b577-475d-996e-bc8f9899eae0 - - - - -] Connection failed: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:897)
