Remove the local onos/core/Pair.java class and replace it with
the corresponding "org.apache.commons.lang3.tuple.Pair" from Apache.
Usage differences:
* "new Pair<>(a, b)" -> "Pair.of(a, b)"
Note that "Pair.of()" returns immutable pair by definition: ImmutablePair
* "Pair.getFirst()" -> "Pair.getLeft()"
"Pair.getSecond()" -> "Pair.getRight()"
Also, few replacements for HashMap and similar containers:
"new HashMap<Foo, Bar>()" -> "new HashMap<>()"
