test: improve getFreePort implementation

[ndr-brt]

What this PR changes/adds

Improve getFreePort implementation, following the camel implementation and comments reported on stackoverflow:
https://stackoverflow.com/a/435579

the idea is to check not only ServerSocket but also DatagramSocket and Socket.

Why it does that

the Address already in use flaky tests still happening from time to time.

Further notes

• had to define 3 different predicates because the 3 *Socket classes doesn't implement any common interface besides Closable (!!!)
