Break it into more manageable code by separating allocation primaries and allocating replicas. Start adding basic unit tests for primary shard allocator.
Our thread pools have support for timeout on a task. To support this, a special background task is schedule to run at timeout. That background task fires and check if the main task is still in the executor queue and then cancels it if needed. Currently we schedule this background task before adding the main task to the queue. If the timeout is very small (in tests we often use numbers like 2 ms) the background task can fire before the main one is added to the queue causing the timeout to be missed.

On top of that:
1) A relocation target shards' allocation id is changed to include the allocation id of the source shard under relocatingId (similar to shard routing semantics)
2) The logic around state change for finalize shard relocation is simplified - one simple start the target shard (we previously had unused logic around relocating state)
Closes#12299
While the GeoJSON spec does say a polygon is represented as an array of LinearRings (where a LinearRing is defined as a 'closed' array of points), the coerce parameter provides users with flexibility to have ES automatically close polygons. This addresses situations like those integrated with twitter (where GeoJSON polygons are not closed) such that our users do not have to write extra code to close the polygon. This code change adds the optional coerce parameter to the GeoShapeFieldMapper.

Currently this target is "yet another way" to run elasticsearch,
which we can't maintain. It also has the problem that it doesnt
ensure its running on the latest source code, doesn't configure
any scratch space properly, won't work with securitymanager, list
goes on.
Even if we made it work, it would break every day, since its untested.
Instead, `mvn package -Drun -DskipTests` will run packaging, and then
startup bin/elasticsearch (like integration tests, but in foreground).
It also enables debugger socket on port 8000, for people that like
IDE debuggers and not system.out.println.
Its a little slower to get started because of all the shading/RPM/DEB
building going on in `package` but that is just what it is right now
until that stuff is moved out.
failsafe uses surefire, which sucks. It also mean integ tests act alien right now.
I would rather have the consistency, e.g. things formatted the same way, running integ tests under security manager, etc.
Store information reports on which nodes shard copies exist, the shard
copy version, indicating how recent they are, and any exceptions
encountered while opening the shard index or from earlier engine failure.

When adding a script to the Groovy classloader, the script name is used
as the class identifier in the classloader. This means that in order not
to break JVM Classloader convention, that script must always be
available by that name. As a result, modifying a script with the same
content over and over causes it to be loaded with a different name (due
to the incrementing integer).
This is particularly bad when something like chef or puppet replaces the
on-disk script file with the same content over and over every time a
machine is converged.
This change makes the script name the SHA1 hash of the script itself,
meaning that replacing a script with the same text will use the same
script name.
