Description of problem:
Command satellite-maintain logs its activity to file /var/log/foreman-maintain/foreman-maintain.log with DEBUG log level in its default configuration.

Compounded with files at /var/log/foreman-maintain not being rotated as per bug 1917422 , this can add up over time and exhaust the space available at /var/log:

# ls -lrt /var/log/foreman-maintain

Version-Release number of selected component (if applicable):
rubygem-foreman_maintain-0.6.13-1.el7sat.noarch

How reproducible:
Always

Steps to Reproduce:
1. Run "satellite-maintain service status" repeatedly

Actual results:
Disk usage at /var/log/foreman-maintain grows by 143KB on each invocation.

Expected results:
A lower log level such as ERROR helps preventing disk space at /var/log from being exhausted.

Additional info:
The default contents of configuration file /etc/foreman-maintain/foreman_maintain.yml already specify ERROR log level, but the line is commented out:

# cat /etc/foreman-maintain/foreman_maintain.yml 
# Directory where the logs are stored.
# The default file is named as /log/foreman_maintain.log
:log_dir: '/var/log/foreman-maintain/'

# Logger levels: mention one of debug, info, warning, error, fatal
# :log_level: 'error'
