Support discovery of new class attributes via script

[shadeon]

A commonly requested feature throughout technical preview is the ability to discover using PowerShell script.

At the moment the SCOM authoring UI doesn't expose any way to create classes and relationships directly, and this is an area where the user really needs to have some understanding of SCOM and what they are doing.

However, it does expose the ability to derive a new class from an existing one and add an additional property (populated by a registry key or WMI Query), and this is often a common case when adding CMDB properties to classes.

this would be very useful. no more building a custom MP in visual studio for an additional property would be very welcomed.
