python-linux-procfs: pflags: Use argparse to create a help option
The purpose of this change was to create a -h, or --help option.
The following changes were made.
1. pflags is now python3 only, since it uses argparse.
2. The handling of pids or process names is improved, instead of a
command separated list (without spaces), the more standard unix way of
space separated command line arguements are used.
This is explained in the help
./pflags -h
usage: pflags [-h] [pid [pid ...]]
Print process flags
positional arguments:
pid a list of pids or names
optional arguments:
-h, --help show this help message and exit
