Clean up KeyRangeIterator classes
* replace KeyRangeConcatIterator's PriorityQeueu with List
* remove KeyRangeIterator.current and simplify
* remove injected exception and tests - not relevant to the current implementation
* expand randomized testing
* inline getCurrent() -> peek(); rename getCount to getMaxKeys
* redefine skipTo contract to not return a value (which saves unnecessary work when skipTo is called multiple times in a row)
* calling hasNext in skipTo is a pessimization; if the iterator is in DONE state, then skipTo will see it and avoid further effort; if it is not, then we are computing a next value that we're just going to throw away
* fix SingleNodeQueryFailureTest - tests now multi and single index
* rationalize/standardize the way we release SSTableIndexes in QueryController
