* Revert "DruidLeaderClientProvider to eagerly instantiate DruidNodeDiscovery when needed so that DruidNodeDiscovery impl cache gets initialized well in time"
This reverts commit f1a2432614ba56ddc2d55fe47e990d17fcfd6129.
* add lifecycle to DruidLeaderClient to early initialize DruidNodeDiscovery so that it has its cache update well in time
When historical caching is enabled, and a select or topN query is
issued, and then a following query with "descending": true is set, the
cached query returns the ascending result (or vice versa), often
resulting in invalid paging identifiers.
The CacheKey for these queries doesn't include the "descending" flag;
this change adds it, and fixes the problem.
* Use trusty for travis jobs.
The distro was set to "precise" in #4572 due to memory issues on trusty,
but we've been seeing performance issues on "precise" recently so let's
see how trusty is working these days.
* Less quiet.
* Adjust memory settings.
* Add back -q option.
* Tweak memory again.
* Adjustments.
* Try squeezing memory a bit more.
* Collapse worker select strategies, change default, add strong affinity.
- Change default worker select strategy to equalDistribution. It is
more generally useful than fillCapacity.
- Collapse the *WithAffinity strategies into the regular ones. The
*WithAffinity strategies are retained for backwards compatibility.
- Change WorkerSelectStrategy to return nullable instead of Optional.
- Fix a couple of errors in the docs.
* Fix test.
* Review adjustments.
* Remove unused imports.
* Switch to DateTimes.nowUtc.
* Simplify code.
* Fix tests (worker assignment started off on a different foot)
Expose version property for so that it may serialize/deserialize correctly
Expose version property for `CustomVersioningPolicy` so that it may serialize/deserialize correctly
Expose version property for CustomVersioningPolicy so that it may serialize/deserialize correctly
Expose version property for `CustomVersioningPolicy` so that it may serialize/deserialize correctly

* Simplify Cursors in QueryableIndexStorageAdapter
* Address comments

* Comments
* Add "round" option to cardinality and hyperUnique aggregators.
Also turn it on by default in SQL, to make math on distinct counts
work more as expected.

It's important when the extractionFn maps null to something other than null.
* Extract helper method.
* Change contracts of VirtualColumns and VirtualColumn methods based on review comments.
* Remove unused import.
* Remove unused method.
* Adjust helper function.
* Adjustments
