In plugins, we are using non consistent naming. We use `elasticsearch-cloud-aws` as the artifactId, which generates a jar file called `elasticsearch-cloud-aws-VERSION.jar`.
But when you want to install the plugin, you will end up with a shorter name for the plugin `cloud-aws`.
```
bin/plugin install cloud-aws
```
This commit changes that and use consistent names for `artifactId`, so `finalName`.
Also changed maven names.
The IndicesModule was made up of two submodules, one which
handled registering queries, and the other for registering
hunspell dictionaries. This change moves those into
IndicesModule. It also adds a new extension point type,
InstanceMap. This is simply a Map<K,V>, where K and V are
actual objects, not classes like most other extension points.
I also added a test method to help testing instance map extensions.
This was particularly painful because of how guice binds the key
and value as separate bindings, and then reconstitutes them
into a Map at injection time. In order to gain access to the
object which links the key and value, I had to tweak our
guice copy to not use an anonymous inner class for the Provider.
Note that I also renamed the existing extension point types, since
they were very redundant. For example, ExtensionPoint.MapExtensionPoint
is now ExtensionPoint.ClassMap.

Settings currently has a classloader member, which any user (plugin
or core ES code) can access to load classes/resources. This is extremely
error prone as setting the classloder on the Settings instance is a
public method. Furthermore, it is not really necessary. Classes that
need resources should load resources using normal means
(getClass().getResourceAsStream). Those that need classes
should use Class.forName, which will load the class with the
same classloader as the calling class. This means, in the few
places where classes are loaded by string name, they will use
the appropriate loader: either the default classloader which loads
core ES code, or a child classloader for each plugin.
This change removes the classloader member from Settings, as
well as other classloader related uses (except for a handful
of cases which must use a classloader, at least for now).
Most of the abstract base test classes we have were previously @Ignored.
However, there were also some other tests ignored. Having two ways to
quiet tests is confusing, and clearly it has caused some tests
to get lost in the fold.
This change moves all base test classes to use the "TestCase" suffix,
which is not picked up by the test class name pattern. It also removes
@Ignore from (almost) all tests, and adds it to forbidden apis.
And since we were renaming, I shorted base test class names to use
"ES" instead of "Elasticsearch". I type this a lot of types a day,
and I have heard others express a similar desire for a shorter name.

[TEST] Verify expected number of nodes in cluster before issuing shardStores request
commit f0f5a1e087255215b93656550fbc6bd89b8b3205

Date: Tue Jul 21 11:27:28 2015 -0600
Ignore EngineClosedException during translog fysnc
When performing an operation on a primary, the state is captured and the
operation is performed on the primary shard. The original request is
then modified to increment the version of the operation as preparation
for it to be sent to the replicas.
If the request first fails on the primary during the translog sync
(because the Engine is already closed due to shadow primaries closing
the engine on relocation), then the operation is retried on the new primary
after being modified for the replica shards. It will then fail due to the
version being incorrect (the document does not yet exist but the request
expects a version of "1").
Order of operations:
- Request is executed against primary
- Request is modified (version incremented) so it can be sent to replicas
- Engine's translog is fsync'd if necessary (failing, and throwing an exception)
- Modified request is retried against new primary
This change ignores the exception where the engine is already closed
when syncing the translog (similar to how we ignore exceptions when
refreshing the shard if the ?refresh=true flag is used).

Correctly list blobs in Azure storage to prevent snapshot corruption and do not unnecessarily duplicate Lucene segments in Azure Storage
This commit addresses an issue that was leading to snapshot corruption for snapshots stored as blobs in Azure Storage.
The underlying issue is that in cases when multiple snapshots of an index were taken and persisted into Azure Storage, snapshots subsequent
to the first would repeatedly overwrite the snapshot files. This issue does render useless all snapshots except the final snapshot.
The root cause of this is due to String concatenation involving null. In particular, to list all of the blobs in a snapshot directory in
Azure the code would use the method listBlobsByPrefix where the prefix is null. In the listBlobsByPrefix method, the path keyPath + prefix
is constructed. However, per 5.1.11, 5.4 and 15.18.1 of the Java Language Specification, the reference null is first converted to the string
"null" before performing the concatenation. This leads to no blobs being returned and therefore the snapshot mechanism would operate as if
it were writing the first snapshot of the index. The fix is simply to check if prefix is null and handle the concatenation accordingly.
Upon fixing this issue so that subsequent snapshots would no longer overwrite earlier snapshots, it was discovered that the snapshot metadata
returned by the listBlobsByPrefix method was not sufficient for the snapshot layer to detect whether or not the Lucene segments had already
been copied to the Azure storage layer in an earlier snapshot. This led the snapshot layer to unnecessarily duplicate these Lucene segments
in Azure Storage.
The root cause of this is due to known behavior in the CloudBlobContainer.getBlockBlobReference method in the Azure API. Namely, this method
does not fetch blob attributes from Azure. As such, the lengths of all the blobs appeared to the snapshot layer to be of length zero and
therefore they would compare as not equal to any new blobs that the snapshot layer is going to persist. To remediate this, the method
CloudBlockBlob.downloadAttributes must be invoked. This will fetch the attributes from Azure Storage so that a proper comparison of the
blobs can be performed.

CLITool: Port PluginManager to use CLITool
In order to unify the handling and reuse the CLITool infrastructure
the plugin manager should make use of this as well.
This obsolets the -i and --install options but requires the user
to use `install` as the first argument of the CLI.
This is basically just a port of the existing functionality, which
is also the reason why this is not a refactoring of the plugin manager,
which will come in a separate commit.

Today everything is tight to having the next version as the latest.
In order to work towards 2.0.0.beta1 we need to fix all the usage of
