cephadm: add tcmu-runner to logrotate config

This process could be used to set up the tcmu-runner
to log to a file much like other ceph daemons

- create /etc/tcmu directory
- create /etc/tcmu/tcmu.conf directory with default options
- change dir to /var/log
- change log level to 4
- add -v /etc/tcmu:/etc/tcmu to tcmu-runner container podman line in unit.run

In order to support this (mostly for debugging) we should
add tcmu-runner to the logrotate config
