Adds boot configuration plugins
BootStatusPolicyPlugin: sets the boot status policy via a configurable option. BCDConfigPlugin: ensures that the boot device has a unique disk id and sets the BCD auto recovery mode. Both actions have corresponding configurable options. Change-Id: I9d41d27c8570f9376d0d3de2f676323b031ddf77 Co-Authored-By: Stefan Caraiman <scaraiman@cloudbasesolutions.com> Implements: blueprint bootconfig-plugin
