pcp-ps seems to botch command arg parsing and -o does nothing

[kmcdonell]

This is wrong on several levels ...

kenj@bozo-vm:~$ pcp-ps -e -o '%cpu' TypeError: ProcessStatOptions.extraOptions() takes 3 positional arguments but 4 were given TypeError: ProcessStatOptions.extraOptions() takes 3 positional arguments but 4 were given Linux 5.15.0-52-generic (bozo-vm) 11/04/22 x86_64 (4 CPU) Timestamp PID TIME CMD 21:07:34 1 00:00:05 systemd

1. TypeError => command line arg parsing is broken
2. output is not connected to -o options (related to 1.?) ... output is always the same irrespective of command line options!
3. Timestamp field is not even mentioned in the man page

#1709 Merge request 1709 will fix this issue

@orasagar Thanks for the fix. Unfortunately, this does not seem to resolve all of the issues.

1. is fixed
2. remains ... it does not seem to matter what the -o options are, the output remains the same.
3. remains

@kmcdonell

2 -o option needs to be used exclusive of any other option .please check the qa/1987 last third test case for it and it has a respective output for that also in 1987.out file . if you want I will mention the same thing in the man page also so that it will not confuse. 3- will be fixed along with other documentation bugs.
