ps(1) AIX-format compatible Golang library

 Psgo is a ps(1) AIX-format compatible golang library extended with various
 descriptors useful for displaying container-related data.
 .
 The idea behind the library is to provide an easy to use way of extracting
 process-related data, just as ps(1) does. The problem when using ps(1) is that
 the ps format strings split columns with whitespaces, making the output nearly
 impossible to parse. Using fork and execute ps also adds some jitter, either
 in the container or filter the output afterwards, further limiting
 applicability.
 .
 This library aims to make things a bit more comfortable, especially for
 container runtimes, as the API allows one to join the mount namespace of a
 given process and will parse /proc and /dev/ from there.
