Instead of resolving the global ordinal for each hit on the fly, resolve the global ordinals during post collect.
On fields with not so many unique values, that can reduce the number of global ordinals significantly.

The default number of clients nodes is randomized between 0 and 1, applied to all cluster scopes (global, suite and test). Can be changed through the newly added `@ClusterScope#numClientNodes`.
In our tests we currently refer to nodes in a generic way. All the tests that either stop or start nodes rely on the fact that those nodes hold data though. Made that clearer as that becomes more important when introducing other types of nodes within the test cluster. Reflected this by adapting and renaming the following methods in `TestCluster`:
- ensureAtLeastNumNodes to ensureAtLeastNumDataNodes
- ensureAtMostNumNodes to ensureAtMostNumDataNodes
- stopRandomNode to stopRandomDataNode
and the following ones in `ElasticsearchIntegrationTest`:
- allowNodes to allowDataNodes
- dataNodes to numDataNodes.
- @ClusterScope#numNodes to numDataNodes
- @ClusterScope#minNumNodes to minNumDataNodes
- @ClusterScope#maxNumNodes to maxNumDataNodes
Added facilities to be able to deal with data nodes specifically, like for instance retrieve a client to a data node, or retrieve an instance of a class through guice only from data nodes.
Adapted existing tests to successfully run although there's a node client around.
Fixed _cat/allocation REST tests to make disk.total, disk.avail and disk.percent optional as client nodes won't return that info.
Closes#5949
Decay functions currently only use the first value in a field that contains
multiple values to compute the distance to the origin. Instead, it should
consider all distances if more values are in the field and then use
one of min/max/sum/avg which is defined by the user.
Relates to #3960closes#5940
during the stop process, we raise network disconnect, so it is valid to raise then while we are in stop mode, and actually, we should not miss any events in such a case.
Typically, this is not a problem, since its during the normal shutdown process on the JVM, but when running a reused cluster within the JVM (like in our test infra with the shared cluster), we should properly raise those node disconnects

Our ordinals currently start at 1, like FieldCache did in older Lucene versions.
However, Lucene 4.2 changed it in order to make ordinals start at 0, using -1
as the ordinal for the missing value. We should switch to the same numbering as
Lucene for consistency. This also allows to remove some abstraction on top of
Lucene doc values.
Close#5871
Separate version check logic for reads and writes for all version types, which allows different behavior in these cases.
Change `VersionType.EXTERNAL` & `VersionType.EXTERNAL_GTE` to behave the same as `VersionType.INTERNAL` for read operations.
The previous behavior was fit for writes but is useless in reads.
This commit also makes the usage of `EXTERNAL` & `EXTERNAL_GTE` in the update api raise a validation error as it make cause data to
be lost.
Closes#5663 , Closes#5661, Closes#5929
When a create document is executed, and its an auto generated id (based on UUID), we know that the document will not exists in the index, so there is no need to try and lookup the version from the index.
For many cases, like logging, where ids are auto generated, this can improve the indexing performance, specifically for lightweight documents where analysis is not a big part of the execution.

Today we use a builder pattern / setters to set relevant information
to Engine#Delete|Create|Index. Yet almost all the values are required
but they are not passed via ctor arguments but via an error prone builder
pattern. If we add a required argument we should see compile errors on that
level to make sure we don't miss any place to set them.
Prerequisite for #5917
Currently the parser accepts queries like
```
"query" : {
"any_query": {
...
},
"any_field_name":...
}
```
The "any_field_name" is silently ignored. However, this also causes the parser
not to move to the next closing bracket which in turn can lead to additional query
paremters being ignored such as "fields", "highlight",...
This was the case in issue #4895
closes issue #4895
Needed for REST backwards compatibility tests, since we need to run older tests with the latest runner, which randomizes shards and replicas, but the tests rely on defaults (5,1).
Done in a generic way based on compatibility versions e.g. `-Dtests.compatibility=1.0.0` allows to run tests in a special manner that is compatibile with 1.0.0 version.
Also moved back randomIndexTemplate to ElasticsearchIntegrationTest (from ImmutableCluster) where all the randomized aspects should be.
