Removed some dead code from the optimizer. find_best() was never being used
in drizzle. it is only used when optimzer_search_depth is set to an esoteric
value that a user would not be aware of. Thus, we can safely remove this
function. This eases understanding of the optimizer also since now there is
only one code path to follow for understanding how an optimal plan is
decided upon.
