MINOR: stats: add stats size as a parameter for csv/json dump

Render the stats size parametric in csv/json dump functions. This is
needed for the future patch which provides dynamic stats. For now the
static value ST_F_TOTAL_FIELDS is provided.

Remove unused parameter px on stats_dump_one_line.

This patch is needed to extend stat support to components other than
proxies objects.
