Disable selinux on containers MON and RGW

Initially MONs and RGW binded /etc/pki/ca-trust/extracted using the :z flag
(introduced to solve an OSP TripleO issue on RHEL - ceph#3638) but using
this flag on that specific folder brought other issues like
https://bugzilla.redhat.com/show_bug.cgi?id=2026953
The z flag prevents local services (like sssd) running on the host accessing
the certificates/files in that folder.
