printer/table: add options to customize

[tormath1]

the current behavior of printer.Table is to return every exported fields of the struct. (except complex fields like structs).

The lib we use allows a certain amounts of customization and we have the printer.Options to pass options to the various printers we have.

it would be nice to have a way to define the things we want to display, the separator, etc. for the printer.Table

imo, table printer is pretty ugly right now, I will look for cleaning outputs to be more readable
