Unassigned meta includes additional information as to why a shard is unassigned, this is especially handy when a shard moves to unassigned due to node leaving or shard failure.
The additional data is provided as part of the cluster state, and as part of `_cat/shards` API.
The additional meta includes the timestamp that the shard has moved to unassigned, allowing us in the future to build functionality such as delay allocation due to node leaving until a copy of the shard is found.

Since the /var/run/elasticsearch directory is cleaned when the operating system starts, the init.d script must ensure that the PID_DIR is correctly created.
Closes#11594
The cache we are using for fielddata reclaims memory lazily/asynchronously. While this
helps with throughput this is an issue when a clear operation is issued manually since
memory is not reclaimed immediately. Since our clear methods already perform in linear
time anyway, this commit changes the fielddata cache to reclaim memory synchronously
when a clear command is issued manually. However, it remains lazy in case cache entries
are invalidated because segments or readers are closed, which is important since such
events happen all the time.

Some of our Java api builders had wrong logic when it comes to serializing the query in json format, resulting in missing fields like _name. Also, regexp parser was ignoring the _name field.

[doc] fix outdated java api examples
Some API have been changed in master. Master documentation should reflect be updated:
* QueryBuilders.queryString is now QueryBuilders.queryStringQuery
* DateHistogram.Interval is now DateHistogramInterval
* Refactoring of buckets in aggs
* FilterBuilders has been replaced by QueryBuilders
Closes#9976.

[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.
[maven] clean pom.xml
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.
This was previously a container for an ObjectMapper, along with the
DocumentMapper that ObjectMapper came from. However, there was
only one use of needing the associated DocumentMapper, and that
wasn't actually used.

Now that doc values are the default for fielddata, specialized in-memory
formats are becoming an esoteric option. This commit removes such formats:
- `fst` on string fields,
- `compressed` on geo points.
I also removed documentation and tests that the fielddata cache is shared if
you change the format, since this is only true for in-memory fielddata formats
(given that for doc values, the caching is done directly in Lucene).
The script APIs have been deprecated long ago we can now remove them.
This commit still keeps the parsing code since it might be used in a
query that is still stuck in transaction log. This issue should be discussed
elsewhere.
Closes#11619
In order to restrict a single set of field type settings for a given
field name across an index, we need the ability to compare field types.
This change adds equals and hashcode, as well as tests for every field
type.
Make sure there is a single place where shard routing move to unassigned, so we can add additional metadata when it does, also, simplify shard routing implementations a bit
