Add timeout for Windows Update Agent (WUA) calls

The SVM agent has a new time-out mechanism that enables one to configure a time-out period for WUA searches. This option prevents the SVM agent from being stuck waiting for the WUA service to return with data. The default timeout is 30 minutes and is configurable via the -- wua-timeout option. A value of zero means the SVM agent will wait indefinitely for the WUA call to respond back.

Example: csia.exe -I -L - wua-timeout 5
