BUG12445: Fix for Hyper-V stuck 8 minutes at boot

Fix for Bug 12445: There is no proper way to distinguish between MS Azure and a local
Hyper-V installation Procedure: try to get the metadata info from the
internal MS metadata service at IP 169.254.169.254 If this fails the system
is running on an local Hyper-V instance wget takes too long to exit if the IP
is not reachable Added --timeout and --tries param to wget to reduce the
duation from 8 minutes to 9 seconds 9 seconds at one try should be enough
