Remove mysql_table_exists() function

This function is intended to check for the existence of a table before
declaring some resource, but this is neither portable (because functions
orun on the master, not the agent) nor one-run idempotent (because the
function would run before mysql is even installed, and would take two
runs to do anything).

The correct way of doing this would be to update the providers and
dependency ordering to handle the conditional states.

Luckily this was never released so it is backwards compatible.
