swim: drop swim_info() function

Swim_info() was a function to dump SWIM instance info to a Lua
table without explicit usage of Lua. But now all the info can be
taken from 1) self member and member API, 2) cached cfg options
as a Lua table in a forthcoming Lua API - this is how
box.cfg.<index> works.
