* Expressions: Add ExprMacros, which have the same syntax as functions, but
can convert themselves to any kind of Expr at parse-time.
ExprMacroTable is an extension point for adding new ExprMacros. Anything
that might need to parse expressions needs an ExprMacroTable, which can
be injected through Guice.

This is useful for putting them behind load balancers or proxies, as it lets
the load balancer know which server is currently active through an http health
check.
Also makes the method naming a little more consistent between coordinator and
overlord code.
* Optional long-polling based segment announcement via HTTP instead of Zookeeper

* optionally add extensions to explicitly specified hadoopContainerClassPath
* note extensions always pushed in hadoop container when druid.extensions.hadoopContainerDruidClasspath is not provided explicitly
* RealtimeIndexTask to support alertTimeout in context and raise alert if task process exists after the timeout
* move alertTimeout config to tuningConfig and document
It wasn't doing anything useful (the sequences were being concatted, and
cursor.getTime() wasn't being called) and it defaulted to Granularities.NONE.
Changing it to Granularities.ALL gave me a 700x+ performance boost on a
small dataset I was reindexing (2m27s to 365ms). Most of that was from avoiding
making a lot of unnecessary column selectors.
* Add SameIntervalMergeTask for easier usage of MergeTask
