We don't shade anymore elasticsearch dependencies, so plugins might include jars in the distribution ZIP file which might not be needed anymore.
For example, `elasticsearch-cloud-aws` comes with:
```

A lot of those files are already distributed with elasticsearch itself so classes are available within the classloader.
We mark all es core dependencies as provided in plugins.
We also remove `groupId` as already defined in parent pom.
And we remove non needed licenses files as some jars are not included anymore in plugins.
Closes#11647.
The change makes rest-spec-api a project in the same way as we build dev-tools. it packages the tests and api in a bundle using the maven-remote-resources-plugin and uses the same plugin in the plugins and core pom to unpack the rest-api-spec into the target directory and references the rest tests there in the test resources.
The main stimulus for this change is that for those using Eclipse the current build does not work. After running `mvn eclipse:eclipse` the Eclipse IDE errors because the rest-api-spec is outside of the project scope, meaning that every time the command is run (required whenever any dependencies change), the class path of all the projects has to be manually fixed.
The delete by query plugin adds support for deleting all of the documents (from one or more indices) which match the specified query. It is a replacement for the problematic delete-by-query functionality which has been removed from Elasticsearch core in 2.0. Internally, it uses the Scan/Scroll and Bulk APIs to delete documents in an efficient and safe manner. It is slower than the old delete-by-query functionality, but fixes the problems with the previous implementation.
Closes#7052
[build] mark elasticsearch as provided in plugins
When we build a plugin, we suppose it will be executed within elasticsearch server.
So we should mark it as `provided`.
If a java developer needs to embed the plugin and elasticsearch, it will make sense to declare both in its `pom.xml` file.
In Maven parent project, in dependency management, we should only declare which versions of 3rd party jars we want to use but not force any scope.
It makes then more obvious in modules what is exactly the scope of any dependency.
For example, one could imagine importing `jimfs` as a `compile` dependency in another module/plugin with:
```xml
<dependency>
<groupId>com.google.jimfs</groupId>
<artifactId>jimfs</artifactId>
</dependency>
```
But it won't work as expected as the default maven `scope` should be `compile` but here it's `test` as defined in the parent project.
So, if you want to use this lib for tests, you should simply define:
```xml
<dependency>
<groupId>com.google.jimfs</groupId>
<artifactId>jimfs</artifactId>
<scope>test</scope>
</dependency>
```
We also remove `maven-s3-wagon` from gce plugin as it's not used.
