Installing SAM w/ Python 3.7

install_sam_python3.7.sh

# there is some trickyness installing AWS SAM CLI on Ubuntu 16.04
# Official documentation recommends using Linux Homebrew... uhm nope.
# https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install-linux.html
# SAM needs Python3.6+ and a blanket install sort fucks up the system and other apps.
