Peter Krempa 41b5e8451b virsh: Add helper to request string arguments with error reporting
This patch adds a helper function with similar semantics to
vshCommandOptString that requests a string argument, but does some error
reporting without the need to do it in the functions themselves.

The error reporting also provides information about the parameter whose
retrieval failed.
