I have reverted some last changes to get logging and network extraction
from context separated from the pipeline again as it has been before.
Feels much better to have it separated within the generated plugins.
I have split the code into various files and beside that I have also
used more flat package structure. I have removed the whole constants for
flag names and environment variables, since nobody got to write these
flags manually anyway as all these variables are assigned to structs
all can benefit form code completion while this lib stays more readable.
