Masakari: copy TLS certificates into containers

From Ussuri, if CA certificates are copied into
/etc/kolla/certificates/ca/, these should be copied into all containers.
This is not being done for masakari currently.

Additionally, we are not setting the [DEFAULT] nova_ca_certificates_file
option in masakari.conf. This depends on masakari bug 1873736 being
fixed to work.

This change fixes these issues.
