Remove ellipsis in box Lua API

Change:
    box.space.name:insert() to box.space.name:insert{}
    box.space.name:replace() to box.space.name:replace{}
    box.space.name:delete() to box.space.name:delete{}
    box.space.name:auto_increment() to box.space.name:auto_increment{}
    box.space.name:select() to box.space.name:select{}
    box.space.name:update() now requires an explicit key and ops
    table.

Remove ellipsis from wrappers which don't strictly need it.
Remove backward-compatible next_equal/next/prev_equal/next/prev
iteration functions.
Cleanup hot_standby.test
