init: Create database indexes during schema creation

We now automatically create the database indexes during schema
creation by parsing our own index creation script(s) and doing
their raw SQL commands one at a time on the underlying database.

To simplify setup we now only perform this work inside of init,
and no longer do it implicitly when the WAR is loaded inside of
a servlet container.
