[RFC PATCH v3 4/5] s3: net: implement json output for ads info

Thu Jul 12 07:04:08 UTC 2018
Add the switch '-j' to 'net' to format the output as JSON.
The rationale is to supply the information in a machine-readable
fashion to complement the text version of the output which is
neither particularly well defined nor locale-safe.
The output differs from that of plain 'info' in that times are
not formatted as timestamps.
Currently affects only the 'net ads info' subcommand.
