CLOUDSTACK-1086: DeployVirtualMachine userdata enhancements
Description:
Currently, userdata sent over to the DeployVMCmd and
updateVMCmd commands can be upto 2K in length, whether
sent over GET or POST. We remove this limitation for
POST to change this limit to 32K. Also enabling lazy
load on userdata to improve performance during reads
of large sized userdata from user VM records.

> Currently querying the userData is using HTTP GET method, with a limit of 2k
> length. Since HTTP GET has a length limit, to support the 32k user data, we
> will use HTTP POST to increase the userData size to 32k. HTTP POST does not
> have a length limit.
> 1. We will use HTTP POST method;
> 2. DB change: We need to modify the VM VO object . The expanded userData will
> be a transient record. The normal VM query still returns the usual userData
> up to 2k. We only return the 32k transient userData when specified.
