Subscribe to this {@link Mono} and <strong>block</strong> until a next signal is
received, the Mono completes empty or a timeout expires. Returns an {@link Optional}
for the first two cases, which can be used to replace the empty case with an
Exception via {@link Optional#orElseThrow(Supplier)}.
In case the Mono itself errors, the original exception is thrown (wrapped in a
{@link RuntimeException} if it was a checked exception).
If the provided timeout expires, a {@link RuntimeException} is thrown.

Note that each block() will trigger a new subscription: in other words, the result
might miss signal from hot publishers.

@param timeout maximum time period to wait for before raising a {@link RuntimeException}

@return T the result
