Document workable log rotation strategies until native log rotation arrives

[geekpete]

Describe the feature:

Provide some advice in the documentation about workable log rotation techniques for existing versions until native logrotation arrives with the fulfilment of #12259

Suggested methods might include:

Using Logrotate

First, set the pid.file option in kibana.yml to have Kibana create a process ID file (use a location where the kibana user has privileges to read/write read/to), e.g.

pid.file: "/var/log/kibana/kibana.pid"

Then using logrotate, add an entry to logrotate.conf, such as:

/var/log/kibana/kibana.stdout {
    daily
    copytruncate
    compress
    missingok
    notifempty
    sharedscripts
    postrotate
    /bin/kill -HUP $(cat /var/log/kibana/kibana.pid 2>/dev/null) 2>/dev/null
    endscript
}

Refer to Linux documentation for your logrotate customization needs.
