Enable to modify params of logrotate-crond.conf

Parameters "minsize" and "notifempty" of /etc/logrotate-crond.conf
in the container logrotate_crond should be changeable even if this
doesn't	comply with GDPR. This is because there might be users who
don't want to comply with it for some reason such as their internal
rule, testing purpose, etc.

This patch adds the following Puppet hieradata.

tripleo::profile::base::logging::logrotate::minsize (default: 1)
tripleo::profile::base::logging::logrotate::notifempty (default: True)
