#   -p <value> : Password for Syncthing GUI. Creates an SSM Parameter with this value (to be referenced by other scripts)
#   -i <value> : Your local Syncthing device-id with which you want to pair your EC2. Creates an SSM Parameter with this value (to be referenced by other scripts)
#   -n <value> : Your local Syncthing device-name with which you want to pair your EC2. Creates an SSM Parameter with this value (to be referenced by other scripts)
