Raise IOException on deleteBlob if the blob doesn't exist
This commit raises an IOException on BlobContainer#deleteBlob
if the blob does not exist, in conformance with the BlobContainer
interface contract. Each implementation of BlobContainer now
conforms to this contract (file system, S3, Azure, HDFS). This
commit also contains blob container tests for each of the
repository implementations.
Closes#18530
In 2.0 we added plugin descriptors which require defining a name and
description for the plugin. However, we still have name() and
description() which must be overriden from the Plugin class. This still
exists for classpath plugins. But classpath plugins are mainly for
tests, and even then, referring to classpath plugins with their class is
a better idea. This change removes name() and description(), replacing
the name for classpath plugins with the full class name.
This commit clarifies the behavior that must be adhered to by any
implementors of the BlobContainer interface. This is done through
expanded Javadocs.

We have both `Settings.settingsBuilder` and `Settings.builder` that do exactly
the same thing, so we should keep only one. I kept `Settings.builder` since it
has my preference but also it is the one that we use in examples of the Java API.
Elasticsearch 5.0 doesn't support indices wiht legacy checksums anymore.
The last time we write legacy checksums was in 1.3.0 which was based
on lucene 4.9 already which means that all files have CRC32 checksums.
All indices that Elasticsearch can read today must be written with
lucene version >= 4.8 anyway so we can drop this layer of backwards
compatibility entirely.
Since we are close to upgrading to Lucene 6.0 we should get rid of this
in a more contiained change than the lucene upgrade.
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.
This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.
Migrated from ES-Hadoop. Contains several improvements regarding:
* Security
Takes advantage of the pluggable security in ES 2.2 and uses that in order
to grant the necessary permissions to the Hadoop libs. It relies on a
dedicated DomainCombiner to grant permissions only when needed only to the
libraries installed in the plugin folder
Add security checks for SpecialPermission/scripting and provides out of
the box permissions for the latest Hadoop 1.x (1.2.1) and 2.x (2.7.1)
* Testing
Uses a customized Local FS to perform actual integration testing of the
Hadoop stack (and thus to make sure the proper permissions and ACC blocks
are in place) however without requiring extra permissions for testing.
If needed, a MiniDFS cluster is provided (though it requires extra
permissions to bind ports)
Provides a RestIT test
* Build system
Picks the build system used in ES (still Gradle)
