The `_create` API is handy way to specify an index operation should only be done if the document doesn't exist. This is currently implemented in explicit code paths all the way down to the engine. However, conceptually this is no different than any other versioned operation - instead of requiring a document is on a specific version, we require it to be deleted (or non-existent). This PR removes Engine.Create in favor of a slight extension in the VersionType logic.
There are however a couple of side effects:
- DocumentAlreadyExistsException is removed and VersionConflictException is used instead (with an improved error message)
- Update will reject version parameters if the upsert option is used (it doesn't compute anyway).
- Translog.Create is also removed infavor of Translog.Index (that's OK because their binary format was the same, so we can just read Translog.Index of the translog file)

It is rarely used and was not consistently handled by different distributions anyway.
This commit also adds a test for specifying CONF_DIR when installing plugins and
starting elasticsearch.

Plugin cli tools configures logging with whatever is in the logging.yml.
If a file appender is configured for any of the logs this will cause creation
of an empty log file. If a plugin was for example installed as root it will
create empty logs at es.home/logs.
This is problematic when for example plugins are installed as root and es is run
as service. Logs will then be created in /usr/share/elasticsearch/logs
and can later not be removed by for example dpkg -r or -purge.
To avoid this, configure the logger to use an appender that writes to the same
output that plugin cli tool does. This allows other components that are called
from Plugin cli tool to write to the same terminal that plugin cli tool writes to
by using the logging mechanism already in place.
The logging conf is not read at all pb plugin cli tool.
As a side effect, the loging level for components that are called
from the plugin command such as the jar hell check can now be configured
with -Des.logger.level which makes it easier to debug the jar hell check.
The field is optional everywhere else but in the serialization methods, which causes problems. Also expanded tests so that they can catch this type of problem.
Closes#13963
These abstractions don't really do anything nor can they be extended.
We can just fold them into IndexModule for now. There are more but they
are tricky due to some test dependencies which I need to resolve first.
Types are still optional, but if you do provide them, they can't be null. Split the existing constructor that accepted nnull into two, one that accepts no arguments, and another one that accepts the types argument, which must be not null.
Also trimmed down different ways of setting ids, some were misleading as they would always add the ids to the existing ones and not set them, the add prefix makes that clear. Left `addIds` method that accepts a varargs argument. Added check for ids not be null.
Today we use a hirachical injector on the shard level for each shard
created. This commit removes the shard level injetor and replaces
it with good old constructor calls. This also removes all shard level plugin
facilities such that plugins can only have node or index level modules.
For plugins that need to track shard lifecycles they should use the relevant
callback from the lifecycle we already provide.
This commit removes and now forbids all uses of
com.google.common.hash.HashCode, com.google.common.hash.HashFunction,
and com.google.common.hash.Hashing across the codebase. This is one of
the few remaining steps in the eventual removal of Guava as a
dependency.

The fix in #13848 has an off by one issue where the first byte of the checksum
was never written. Unfortunately most tests shadowed the problem and the first
byte of the checksum seems to be very likely a 0 which causes only very rare
failures.

Right now, we allow allocation if there is only a single node in the
cluster. it would be nice to fail open when there is only one data node
(instead of only one node total).

Lucene's RateLimiter can do too much sleeping on small values (see also #6018).
The issue here is that calls to "pause" are not properly guarded in "restoreFile".
Instead of simply adding the guard, this commit uses the RateLimitingInputStream similar as for "snapshotFile".
Closes#13828
Today we are relying on calling Store.verify on the closed stream to validate the
checksum. This is still necessary to catch file truncation but for an actually corrupted
file or checksum we can fail early and check the checksum against the actual metadata
once it's been fully written to the VerifyingIndexOutput.

Nuke ES_CLASSPATH appending
Out of box, ES expects its stuff to be in particular places. We should not be appending to ES_CLASSPATH, allowing users to specify stuff there, like we do in elasticsearch.bin.sh
If the user sets it, its not going to work out of box.

Fail hard on empty classpath elements.
This can happen easily, if somehow old 1.x shellscripts survive and try to launch 2.x code.
I have the feeling this happens maybe because of packaging upgrades or something.
Either way: we can just fail hard and clear in this situation, rather than the current situation
where CWD might be /, and we might traverse the entire filesystem until we hit an error...

When the plugin manager does not find in `plugin-descriptor.properties` the exact same elasticsearch version it was built on
as the current elasticsearch version, it fails with a message like:
```
ERROR: Elasticsearch version [2.0.0-beta1] is too old for plugin [elasticsearch-mapper-attachments]
```
Actually, the message should be:
```
Plugin [elasticsearch-mapper-attachments] is incompatible with Elasticsearch [2.0.0.beta2]. Was designed for version [2.0.0.beta1].
```
The opposite is true. If you try to install a version of a plugin which was built with a newer version of elasticsearch, it will fail the same way:
```
Plugin [elasticsearch-mapper-attachments] is incompatible with Elasticsearch [2.0.0.beta1]. Was designed for version [2.0.0.beta2].
```
