Sets the specified {@code checkIntervalMills} for checking health in milliseconds.
If not set {@value DEFAULT_CHECK_INTERVAL_MILLIS} is used by default.

<p>Note that the {@code checkIntervalMillis} should be configured with {@link #checkUri(URI)}.
Otherwise, the {@link #build()} method will throws {@link IllegalStateException}.
