After enabling Embedded Ansible and running yum update once the following repos are added:

[root@cf46 ~]# ls /etc/yum.repos.d/ -l
total 412
-rw-r--r--. 1 root root    211 May 18 11:06 ansible-el7.repo
-rw-r--r--. 1 root root    222 May 18 11:06 ansible-tower.repo
-rw-r--r--. 1 root root    640 May 18 11:06 epel-7.repo
-rw-r--r--. 1 root root    327 May 18 11:06 jlaska-rabbitmq.repo
-rw-r--r--. 1 root root    440 May 18 11:06 pgdg-96-centos.repo

Following with yum update again and the following packages now show updates based on these non-Red Hat repos:
