Subject: [PATCH] Set log_size_max size for podman logs

Sometimes the logs can take over 20GB in few weeks.
By setting 1GB as log_size_max should avoid situation that we are
out of the disk few times per week.
The feature has been added into the podman containers.conf file in
podman 2.2.0 release [1], but on Centos 7, version is below 2.2.0.
According to the libpod.conf man [2], that option should be also
available in podman 1.6.4, but it is located in libpod.conf file.
More info [3].
