* Cache: Add maxEntrySize config.
The idea is this makes it more feasible to cache query types that
can potentially generate large result sets, like groupBy and select,
without fear of writing too much to the cache per query.
Includes a refactor of cache population code in CachingQueryRunner and
CachingClusteredClient, such that they now use the same CachePopulator
interface with two implementations: one for foreground and one for
background.
The main reason for splitting the foreground / background impls is
that the foreground impl can have a more effective implementation of
maxEntrySize. It can stop retaining subvalues for the cache early.

* Remove some unnecessary task storage internal APIs.
- Remove MetadataStorageActionHandler's getInactiveStatusesSince and getActiveEntriesWithStatus.
- Remove TaskStorage's getCreatedDateTimeAndDataSource.
- Remove TaskStorageQueryAdapter's getCreatedTime, and getCreatedDateAndDataSource.
- Migrated all callers to getActiveTaskInfo and getCompletedTaskInfo.
This has one side effect: since getActiveTaskInfo (new) warns and continues when it
sees unreadable tasks, but getActiveEntriesWithStatus threw an exception when it
encountered those, it means that after this patch bad tasks will be ignored when
syncing from metadata storage rather than causing an exception to be thrown.
IMO, this is an improvement, since the most likely reason for bad tasks is either:
- A new version introduced an additional validation, and a pre-existing task doesn't
pass it.
- You are rolling back from a newer version to an older version.
In both cases, I believe you would want to skip tasks that can't be deserialized,
rather than blocking overlord startup.

* fix opposite day in ImmutableDruidServer.equals
* simplify
False failures on Travis due to spurious timeout (in turn due to noisy
neighbors) is a bigger problem than legitimate failures taking too long
to time out. So it makes sense to extend timeouts.
* Fix SQL Server select query in createInactiveStatusesSinceQuery() method.
SQL server does not support LIMIT N in select queries. Instead it has TOP N to limiting number of query results.
And TOP N is already added in the select statement as per maxNumStatuses value.
* Add parentheses for TOP in SELECT statement as SQL Servers no longer support TOP without parentheses.
* Add the new tasks api in overlordResource
It takes 4 optional query params
* state(pending/running/waiting/compelte)
* dataSource
* interval (applies to completed tasks)
* maxCompletedTasks (applies to completed tasks)
If all params are null, the api returns all the tasks
* Add the state to each task returned by tasks endpoint
* divide active tasks into waiting, pending or running
* Add more unit tests
* Add UNKNOWN state to TaskState
* Fix the authorization calls
* WIP: PR comments
Added new class to capture task info for caching
Other refactoring
* Refactoring : move TaskStatus class to druid-api
so it can be accessed within server
And other related classes like TaskState and TaskStatusPlus are in api
* Remove unused class and apis accessing it
* Add a separate cache for recently completed tasks
This is to mainly capture the task type from payload
* Ignore a test
* Add a RuntimeTaskState to encompass all states a task can be in
* Revert "Add a RuntimeTaskState to encompass all states a task can be in"
This reverts commit 2a527a0731.

* the check should probably test the other way around
* documentation should put the option in the right place
* examples have a superfluous backslash
* add test to verify correct behavior
* switch to Path and test with jimfs
Path allows to use different filesystems.
Jimfs provides an actual (in memory) filesystem.
This also allows more complex test scenarios.
The behavior should be unchanged by this commit.
* Revert "switch to Path and test with jimfs"
This reverts commit 8b9a418d65.
* VersionedIntervalTimeline: Optimize construction with heavily populated holders.
Each time a segment is "add"ed to a timeline, "isComplete" is called on the holder
that it is added to. "isComplete" is an O(segments per chunk) operation, meaning
that adding N segments to a chunk is an O(N^2) operation. This blows up badly if
we have thousands of segments per chunk.
The patch defers the "isComplete" check until after all segments have been
inserted.
* Fix imports.
