[BUG ACS 4.3] Cannot delete and re-add IP range on guest network

[ilya musayev]

Hi All,

Just trying to raise awareness for the issue we are seeing on 4.3 with 
IP management of guest vlans: details of JIRA issue 
https://issues.apache.org/jira/browse/CLOUDSTACK-6312

------
I've realized that i over allocated IP addresses for some of guest 
VLANs, so i went ahead and deleted all guests using the VLAN in question 
to free ip space in use.

2 issues noticed:

1) The router that were using Guest VLAN in question after deletion did 
not release the IP space, the record had to be de-allocated via mysql

2)After the guest ip range has been deleted, i attempted to add the same 
network with smaller IP range, cloudstack now claims that IP range does 
not match - while it does!

Regards
ilya
