CLOUDSTACK-9155 make sure logrotate is effective
Many processes on the VRs log to cloud.log. When logrotate
kicks in, the file is rotated but the scripts still write
to the old inode (cloud.log.1 after rotate). Tis quickly
fills up the tiny log partition.
Using 'copytruncate' is a tradeoff, there is a slight
change of missing a log entry, but in the old situation
we were missing all of them after logrotate.

> Key: CLOUDSTACK-9155
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9155
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Virtual Router
> Affects Versions: 4.6.0, 4.7.0, 4.6.1
> Reporter: Remi Bergsma
> Assignee: Remi Bergsma
> Priority: Critical
> Fix For: 4.7.0, 4.6.2

>
> Many processes log into the cloud.log file. When log rotate is called, many
> of them keep logging to the old inode and fill up the disk like that.
> These have cloud.log open:
> ```
> root@r-1023-VM:~# lsof| grep cloud | awk {'print $1'} | sort -u
> apache2
> conntrack
> keepalive
> logger
> passwd_se
> _plutoloa
> _plutorun
> python
> xl2tpd
> ```
> Current log rotate config:
> ```
> /var/log/cloud.log {
> rotate 4
> daily
> size 10M
> missingok
> notifempty
> compress
> delaycompress
> }
> ```
> After log rotate this happens:
> ```
> root@r-996-VM:/etc# lsof | grep cloud.log.1
> _plutorun 767 root 3w REG 202,10 26054919
