This approach allowed for easy NavigationSystem's config update with NavSystemConfigOverride's properties. NavSystemConfigOverride can now specify if it wants to fully override the pre-existing nav sys instance or if it just wants to append new information (like supported agents) to the existing navigation system instance. There's also an option to do nothing if there's already a navigation system present. This CL rolls-back a bunch of temp fixes done in past couple of days. #rb Yoan.StAmant Yoan.StAmant #ROBOMERGE-OWNER: mieszko.zielinski #ROBOMERGE-AUTHOR: mieszko.zielinski #ROBOMERGE-SOURCE: CL 8187661 via CL 8193395 via CL 8207613 #ROBOMERGE-BOT: (v401-8057353) [CL 8207758 by mieszko zielinski in Main branch]
