When command line tools accept passwords, remove them from the command line so that they don't get visible in '/proc/pid/commandline'. There is no common method to access the original ARGV vector and modify it from Python. Since this mostly affects Linux systems where IPA services run, we expect use of GNU libc and thus can rely on internal glibc symbols. If they aren't available, the code will skip removing passwords.
