Revert "CLOUDSTACK-3424 Fixed dhcphosts entry and also dhcp_relase for ipv6"

This reverts commit f37567ef45fe6e41469a176d387e91840bfae23c.
This deletes the duplicate entry when new vm came with deleted vm ip.
So will not fix the bug CLOUDSTACK 3424 fully. So this changes will be committed into new

> IPV6 - When a Vm is expunged and a new Vm is deployed with the same name , /etc/dhchosts.txt
has 2 entries with the same name
> Steps to reproduce the problem:
> Create a ipv6 network.
> Deploy a Vm with name - test456.
> Destroy this VM. Wait for it to be expunged.
> Deploy another Vm with same name - test456.
> We see that there are 2 entries in the router with the same name "test456" resolving
to 2 different ipv6 addresses.

> Attaching management server logs:
> Have 2 entries for the same name is a problem.
> Is it also a problem to have the same ipv6 address associated with 2 different vms with
different Vm names ( 1 expunged and 1 active , in my case "test456" which is expunged and
"testyoyo1" which is active) ?
