Description of problem:
capsule-remove does not delete old certificates.

Version-Release number of selected component (if applicable):
- Red Hat Satellite v 6.1.7
- capsule-installer-2.3.24-1.el7sat.noarch 

Issue:

capsule-remove does not delete old certificate rpms. In katello-remove script, "/var/www/html/pub/katello-ca*.rpm" is removed, but it's missing in capsule-remove. That is why we have multiple versions of katello-ca-consumer. 

Confirmed by checking and comparing the files from "/usr/share/capsule-installer/bin/capsule-remove" && "/usr/share/katello/script/katello-remove" we can see that for 'CERT_FILES' section is missing to mention  for removal of "/var/www/html/pub/katello-ca*.rpm" whereas katello-remove has it scripted.

    /etc/pki/tls/certs/pulp_ssl_cert.crt
    /var/www/html/pub/katello-ca*.rpm
)


Expected results:
capsule-remove should delete old certificates from /var/www/html/pub/.
