This feature enables adding of guest ip ranges (public ips) form different subnets.
In order to provide the dhcp service to a different subnet we create an ipalias on the router. This allows the router to listen to the dhcp request from the guest vms and respond accordingly. Every time a vm is deployed in the new subnet we configure an ip alias on the router. Cloudstack uses dnsmasq to provide dhcp service. We need to configure the dnsmasq to issue ips on the new subnets. Added a new class dnsmasqconfigurator which generates the dnsmasq confg file, this file replaces the old config in the router.
The details of the alias ips are stored in db in the nic_ip_alias table. Every time a new subnet is added one of the ip from the subnet is used to configure the ip alias.
I have pushed the code to https://github.com/bvbharatk/cloud-stack/tree/Cloudstack-702 , also rebased the code with master.
I need to test the code for advanced sg enabled network using kvm.
I have added the unit test
Marvin tests are at https://git-wip-us.apache.org/repos/asf?p=cloudstack.git;h=53e4965
Also accomodated some of the changes suggested by koushik.
corrected the import statements. renamed the IpAlias command to createIpAlias command.
This feature supports only ipv4
This feature provides resetting a SSH key for an existing VM which means,
setting the old ssh key that is assigned to the VM previously with the new ssh
key.

For LB device in inline mode, the ip deployer(the owner of public ip) is the
firewall in front of it, not itself. So check if it's inline or not, if it's
inline, return the firewall as ip deployer
The code that would propage userdata to router, when updateVirtualMachine api
is called, was missing. As per the docs [0], userdata should be a base64 encoded
string upto 2KB which is put on domr's html directory adn using HTTP GET the
userdata information can be obtained from the domr.
The updateVirtualMachine api [0] would accept a base64 encoded string
and decoded and put into the domr's /var/www/html/userdata/<uservm ip>/user-data
file. The operation does not require the VM to be in stopped state, though it is
advised to stop and call this api in case the user vm has a script which gets
the userdata information from domr while starting.
For example, this script can be used to fetch the data:
server_ip=$(grep dhcp-server-identifier /var/lib/dhclient-eth0.leases | tail -1 | awk '{print $NF}' | tr '\;' ' ')
wget http://${server_ip}/latest/user-data
This feature can be useful, for example to use into puppet facts [1], or to do
automation and horizontal scaling etc. based on userdata.

2) Don't allow to add new networks/implement existing ones for VPC in Disabled state. Disabled state indicates that there was unsuccessful attempt to remove the VPC, and the further cleanup will be taken care of by cleanup thread.

Summary of Changes:
- created a generic way for LB rule validations, so as LB device(like Haproxy) specific validations can be done syncronously.
- Removed asyncronous validations from Haproxy and done syncronously.
Introduce the concept of Ip Deployer. The IP deployer would be responible for
apply IP to the element. Most element's IP deployer is itself, but it can be
someone else if we want to implement inline mode in the future.
