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
Current kvm agent will silently ignore many exception, and there's no
way to see what really happened. This patch will log in trace level log
that was silently ignored. And also, it will fix huge bare Exception
catch, which is very harmful because it also catches RuntimeException.
Detail: SetVPCStaticNatRules was one command that was left off of the initial
VPC implementation. This adds it in.

Implements
SetupGuestNetworkCommand,SetNetworkACLCommand,SetSourceNatCommand,IpAssocVpcCommand,SetPortForwardingRulesVpcCommand.
Passes basic functionality, though I'm sure there may be some honing to
do.
Also fixes a few minor things found along the way:
vpc_guestnw.sh wasn't successfully setting up apache due to default
listen IP of 10.1.1.1
vpc_guestnw.sh was referencing a 'logger_it' function, replaced with
'logger -t cloud'
system vms were running with OS type "Debian GNU/Linux 5.0(32-bit)",
which was not found in the KVMGuestOsMapper
the Xen implementation of SetupGuestNetworkCommand had apparently
copied its catch message from UnPlug Nic, fixed string

Add BridgeVifDriver and move current vif implementation to it.
- remove dependency on VirtualRoutingResource.
- factor out some of the networking code in LibvirtComputingResource
to BridgeVifDriver.
Add base class for KVM VifDriver.
Add VifDriver Interface for KVM.

[Dropped Vmware support in this commit, due to lack of VMware support in VPC now]
Conflicts:
plugins/hypervisors/vmware/src/com/cloud/hypervisor/vmware/resource/VmwareResource.java
Summary of changes :
- Added a new flag -s to ipassoc command to carry if the ip address is
used for SNAT or not.
- SNAT is completly decoupled from the first flag. first flag is used
to decide if the ip address is first ip address of the interface.
- -s and -f are independent, SNAT can be enabled on the non-first ip
also.
Summary of changes:
- Mutiple routing table for each public interface is added (previously there is only one routing table ). when the packet is send out of public interface corresponding per-interface routing table will be used. per-interface routing table will modified when ever ip/interface added/deleted.
- New parameter is added to ipassoc command to include the default gateway for every interface/ip. prevously it is using only one public interface to send out, default gateway is obtained at the boot up time.
- In the DNAT case. In the revese path(from guest vm to outside, or when DNAT packet receives from the eth0) the public ip/source ip will not be available till POSTROUTING. to overcome this, DNAT connection are marked with routing table number at the time of connection creation, in the reverse path the routing table# from DNAT connection is used to detect per-interface routing table.
