Added timing-tracker in src/introspection/timing-tracking.lisp

fixes #2037, refs #1744

The `timing-tracker' class applies the basic NTP algorithm to estimate
clock offsets of remote hosts as well as communication latencies of
remote hosts and processes.

  • src/introspection/protocol.lisp (timing-tracker-clock-offset): new
    generic function; return estimated clock offset
    (timing-tracker-latency): new generic function; return estimated
    communication latency
    (timing-tracker-to-local-clock): new generic function; transform
    timestamp from remote clock to local clock
  • src/introspection/timing-tracking.lisp: new file; contains
    `tracked-quantity' and `timing-tracker' classes
  • test/introspection/timing-tracking.lisp: new file; contains unit tests
    for the `timing-tracker' class
  • rsb-introspection.asd (system rsb-introspection): added file
    src/introspection/timing-tracking.lisp
    (system rsb-introspection-test): added file
    test/introspection/timing-tracking.lisp
