Consider implementing curl-based repo cloning without git/git-lfs mess

[bwsw]

The idea is that many people do not have git-lfs installed and thus encounter pseudo-errors. To overcome that, we can try pack all savant as artifacts and provide a script to install it like

# VERSION=develop
# VERSION=0.4.5
# DIRECTORY=develop (by default is equal to branch/tag)
#
curl -O install.sh https://get.savant-ai.io/install.sh  
sh ./install.sh install develop
cd develop/Savant

sh ./install.sh prune develop # prunes everything in `develop` and images
sh ./install.sh update develop # updated images and unmodified source code/for modified asks to keep the original or replace with new.

Which downloads sources, images, unzips, and checks dependencies on L4T and X86. It also can clear and reinstall.
