[Plugin] Allow selectively disabling postprocessing

Adds two mechanisms by which users can choose to disable postprocessing
of collected information.

First, is a global method exposed via the `--no-postproc` option. Using
this option will skip postprocessing for all plugins.

Second, is a per-plugin option exposed via a new 'postproc' plugin
option. This is set to _True_ by default (meaning yes, perform
postprocessing), which users can set to False or off to disable
postprocessing for that plugin only; e.g. `-k podman.postproc=off`

Closes: #286
Resolves: #1862
