CLOUDSTACK-7974: remove old hostname entry for a VM when adding a VM
When adding a VM, it adds an entry to /etc/hosts file on the VR but does not
clear up any older entries for the VM with a same name. The fix uncomments the
command that removes any old entries in the VM.

> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Virtual Router
> Affects Versions: 4.3.0
> Reporter: Yiping Zhang
> Assignee: Rohit Yadav
> Fix For: 4.5.0, 4.6.0, 4.4.2, 4.4.3, 4.3.2
>
>
> We have noticed that entries for hosts which have been destroyed for a long
> time still exist in both /etc/dhcphosts.txt and /etc/hosts files on our
> Virtual Routers.
> To reproduce this bug, just create an instance, note down its MAC and IP
> address, then destroy the instance from web UI. Now check virtual router,
> and you will find that the entries still exist in /etc/dhcphosts.txt and
> /etc/hosts files.
> I did a bit more digging on virtual router, and immediately noticed the
> following:
> 1. /root/edithosts.sh script is only called when an instance is created, but
> not when an instance is destroyed.
> 2. After reading /root/edithosts.sh script, I am pretty certain that the
> function of this script is to add info about newly created instances into
> /etc/hosts and /etc/dhcphosts.txt files. So the script should really be
> renamed as /root/addhosts.sh to reflect its true function.
> 3. there is no script to properly delete entries from /etc/hosts and
> /etc/dhcphosts.txt file when instances are destroyed
