Add logrotate.d script to packages.cloudant.com files

[taris]

The installation packages on packages.cloudant.com are missing a logrotate script for keeping the bigcouch logs small and handy.

For example i am currently using this script:

/opt/bigcouch/var/log/*.log {
        daily
        missingok
        rotate 10
        copytruncate
        compress
        delaycompress
        notifempty
}

Since adding the following logrotate script, bigcouch crashes about 1 out of 10 times at the same time the script gets executed.

/storage/log/bigcouch.log {
rotate 100
daily
dateext
missingok
notifempty
copytruncate
compress
}
