Default (take2)Add "Migrate" to VirtualMachine-menu in the individual VM view

Hi, Cole

I cleared all the problems about your comment.
I show the following the summary of this patch
and a problem about doing "Migrate" from individual VM view.

[Summary]
1. Move the logic that get available host from manager.py to engnine.py.

2. Don't show a host of the different hypervisor in available host list.

3. Change the message from "is migrated from" to "will be migrated from".

4. Add "Migrate" to VirtualMachine-menu in the individual VM view.

VirtualMachine
|
+- Run
Pause
Shutdown
Save
---------------
Migrate ----> host1.example.com
--------------- host2.example.com
Take Screenshot host3.example.com

[Problem]
After I do "Migrate" from the individual VM view,
the view shows a information of the VM on not destination host.
But, I think that the view should show a information of the VM
on destination host.

How about this problem?


Thanks,
Shigeki Sakamoto.
