Only DHCP entry need to know if no one apply the entries(when VM is starting
up), other rules should be safe when return true anyway.

Changes:
- While listing UP hosts in the cluster of the host, the query has changed and now also considers the Host 'resourceState' field and picks only those hosts that have value 'enabled'.
This query result does not include the host being put in maintainance; unlike the earlier query that used to include it.
- But the logic to find out if this is the last host in the Cluster is not updated and has a bug when it compares the list size.
- Fixed this.
2) Added new api - changeServiceForSystemVm - to support service offering upgrade for system vms
3) Removed global config parameters that are not in use anymore: consoleproxy.ram.size, consoleproxy.cpu.mhz, secstorage.vm.ram.size, secstorage.vm.cpu.mhz

2) Increase concurrency level for clustering message delivery

1) Drop synchronized call semantic for ClusterManagerImpl.broadcast()
2) Have no choice now but to use an unbound thread pool to notify upper layer. This is to prevent thread starvation when we have cross-management server waitings.

It's not a elegant fix. The status for firewall rules should remain unchanged
before/after ip association/disassociation. But the related change is tricky
than this fix, may not get enough test for 3.0.1. So we would apply existed
firewall rules again, which would work, just result in some unnecessary
commands.

Fixed as described in the bug.
* CreateVlanIpRangeCmd still accept account/domainId info
* if account owns:
- one Isolated network with source nat service enabled, use this network
- more than one Isolated network with source nat service enabled - error out
- none Isolated networks with source nat service enabled, create it only in
case when there is an Isolated network offering with Availability=Required and
source nat service enabled.
The routing table with two nics may be messed up, due to we sent same
router(gateway) information from different DHCP server, in order to specify
default gateway. E.g.
Network A: 192.168.1.0/24, gw 192.168.1.1
Network B: 192.168.2.0/24, gw 192.168.2.1
User VM: Nic 1 connect to network A, get ip 192.168.1.10; nic 2 connect to
network B, get ip 192.168.2.10.
Set network A as the default network of user VM.
Currently we would send this information to user VM through DHCP offer:
In network A: dhcp-option:router 192.168.1.1
In network B: dhcp-option:router 192.168.1.1
So both NIC in the guest VM would receive 192.168.1.1 as router(gateway).
But, in CentOS 5.6, dhclient-scripts try to tell if the gateway is reachable
for current subnet.
So when we try to enable nic 2(eth1) of user VM, dhclient would receive:
IP: 192.168.2.10
Mask: 255.255.255.0
Router: 192.168.1.1
Then it would found that the specified gateway(router) is not within its own
subnet(192.168.2.0/24). But since we send out this ip(192.168.1.1) as the
gateway for it, dhclient thought that it should got someway to access the
network through this IP. So it would execute:
ip route add 192.168.1.1 dev eth1
ip route replace default via 192.168.1.1 dev eth1
But it can never reach 192.168.1.1(which is in the eth0's subnet and the
gateway of eth0) by go through eth1 interface. So it is messed up.
We've tested Windows 2008 R2, CentOS 5.3, CentOS 5.6 and Ubuntu 10.04. Windows
and Ubuntu are fine with above policy.
To solve this, we send different dhcp:router option according to the guest OS
type now.
We may need expand this list later, but for now we only know that CentOS and
RHEL would behavior in this way.
