* Add metrics for Query Count statistics
This PR adds a new metrics monitor “QueryCountStatsMonitor” which emits
three new metrics -
1) query/success/count - number of successful queries
2) query/failed/count - number of failed queries
3) query/interrupted/count - number of interrupted/timedout queries
fix bindings
* make fields final
* fix imports
* AsyncQueryForwardingServlet implement QueryStatsProvider
* remove unused import
* add first and last aggregator
* add test and fix
* moving around
* separate aggregator valueType
* address PR comment
* add finalize inner query and adjust v1 inner indexing
* better test and fixes
* java-util import fixes
* PR comments
* Add first/last aggs to ITWikipediaQueryTest
* Thrift ingestion plugin
1. thrift binary is platform dependent, use scrooge to generate java files to avoid style check failure
2. stream and hadoop ingesion are both supported, input format can be sequence file and lzo thrift block file.
3. base64 and protocol aware
change header

* Remove thread.sleep
* option to reset offset automatically in case of OffsetOutOfRangeException
if the next offset is less than the earliest available offset for that partition
* review comments
* refactoring
* refactor
* review comments
* Use Long timestamp as key instead of DateTime.
DateTime representation is screwed up when you store with an obj
and read with a different DateTime obj.
For example: The code below fails when you use DateTime as key
```
DateTime odt = DateTime.now(DateTimeUtils.getZone(DateTimeZone.forID("America/Los_Angeles")));
HashMap<DateTime, String> map = new HashMap<>();
map.put(odt, "abc");
DateTime dt = new DateTime(odt.getMillis());
System.out.println(map.get(dt));
```
* Respect timezone when creating the file.
* Update docs with timezone caveat in granularity spec
* Remove unused imports
* Add "like" filter.
* Addressed some PR comments.
* Slight simplifications to LikeFilter.
* Additional simplifications.
* Fix comment in LikeFilter.
* Clarify comment in LikeFilter.
* Simplify LikeMatcher a bit.
* No use going through the optimized path if prefix is empty.
* Add more tests.
* URIExtractionNamespace: Treat null values in lookup maps as missing entries.
This is useful when many logical lookups are derived from the same base JSON file,
and some lookups' values may be unknown sometimes.
* Add test, logging message, and address other comments.
* Update docs.
* Support string type in math expression
