Bug description:
  [Description]

  After the MR part of this bug report:
  https://bugs.launchpad.net/ubuntu/+source/mysql-8.0/+bug/1850980

  logrotate returns an error when running the mysql log rotation script
  if the mysql service is disabled.

  It is expected of logrotate not to return an error if the service is disabled since a disabled service will not generate logs to rotate anyways.
  I have written a fix that checks first the status of the mysql service before running the rest of the log rotate script.

  [Test Plan]

  Run the following commands, and verify the output of logrotate:

  $ sudo apt install mysql-server

  $ sudo systemctl stop mysql.service

  $ sudo logrotate -f /etc/logrotate.conf

  If no error is returned by logrotate it means the fix was successful,
  else the following error is shown:

  error: error running shared postrotate script for '/var/log/mysql.log
  /var/log/mysql/*log '

  
  [Where problems could occur]

  Since the changes is related to logs, possible issues may be that the script falsely detects that the mysql service is disabled and not rotate the logs.
  Any problems resulting from this patch are expected to only be limited to log rotation.
