AbstractInfinispanTest.eventually() default poll interval is too long

Some of the AbstractInfinispanTest.eventually() overloads use a poll interval of 500ms, which is too long.

The overloads that use a message supplier, and eventuallyEquals(), use a dynamic polling interval, starting at 65ms by default. All the overloads should use the same strategy, and the overloads that use an explicit polling interval should be removed.
