Work toward ONOS-1451: Separate Event Key space per instance
Misc changes and cleanup (Step 2):
* Added OnosInstanceId field to class TopologyEvent. For now it is
just assigned, but is not used.
* Minor refactoring of class TopologyEvent so it will be easier to make it
immutable after its its internals and usage are inalized.
* Modified the signature of method PathIntentMap.getIntentsByLink()
to use LinkTuple for the lookup instead of LinkEvent.
* Replaced (only inside onos/core/topology) the usage of Apache's
Validate with Google's Preconditions for null-checking and assignment.
With Apache's Validate we have to use two statements:
Validate.notNull(foo);
this.foo = foo;
With Google's Preconditions we can do it with a single statement:
this.foo = checkNotNull(foo);
NOTE: Apache's commons-lang version 3.x adds Google's semantics.
In the future, we need to decide (across all ONOS code) whether
to use Google's Preconditions or Apache's Validate 3.x
* Removed one of the LinkEvent convenience constructors, because it is used
only in 1-2 places in the unit tests, and nowhere in the main code.
* Few other (minor) cleanup changes
