docker: fixed bad stopping: - use exec when it was missing, so the TERM signal is properly catched, and containers can be stopped instead of being killed after 10s - for a unknown reason, exec and su don't handle correctly "$@" with Docker in base.scripts/sat. It's working as expected when launched from withing a running container, but not when launched with "docker run", so a workaround is used with trap and wait

#!/usr/bin/env python2
# This script simulate prosodyctl adduser/passwd/deluser and call it on the prosody container
import sys, xmlrpclib

proxy = xmlrpclib.ServerProxy("http://prosody:9999/")
def pwd():
    pwd1=raw_input(); pwd2=raw_input(); assert pwd1==pwd2
    return pwd1

password = pwd() if sys.argv[1] in ["adduser", "passwd"] else ""
sys.exit(proxy.prosodyctl(sys.argv[1], sys.argv[2], password))
