rv: Add support for LTL monitors

While attempting to implement DA monitors for some complex specifications,
deterministic automaton is found to be inappropriate as the specification
language. The automaton is complicated, hard to understand, and
error-prone.

For these cases, linear temporal logic is more suitable as the
specification language.

Add support for linear temporal logic runtime verification monitor.
