log sizes

A new perfSONAR host admin reported recently that their host stopped working because /var reached 100% usage.

Things could be immediately improved if perfSONAR shipped with log rotation and compression for all perfsonar-tool kit logs. Presently,
the toolkit does ship a logrotate configuration that does not rotate nor compress old logs, except swamp logs.

It could be shipped with something like
'''
/var/log/perfsonar/*.log {
sharedscripts
size 100M
rotate 54
compress
compresscmd /bin/bzip2
delaycompress
notifempty
missingok
postrotate
/bin/kill -HUP cat /var/run/syslogd.pid 2> /dev/null 2> /dev/null || true
/bin/kill -HUP cat /var/run/rsyslogd.pid 2> /dev/null 2> /dev/null || true
endscript
}
'''

In addition the documentation could advise sites about using OS installs with separate /var partition with suitable size.

A 64GB partition should be suitable for most hosts if rotation with compression is deployed.
