Observe Reactive Streams signals matching the passed filter {@code options} and
trace them using a specific user-provided {@link Logger}, at the given {@link Level}.
<p>
Options allow fine grained filtering of the traced signal, for instance to only
capture onNext and onError:

@param logger the {@link Logger} to use, instead of resolving one through a category.
@param level the {@link Level} to enforce for this tracing Flux (only FINEST, FINE,
INFO, WARNING and SEVERE are taken into account)
@param showOperatorLine capture the current stack to display operator class/line number (default in overload is false).
@param options a vararg {@link SignalType} option to filter log messages

@return a new {@link Flux} that logs signals
