Adrien Grand d8d8666877 Remove `index_name` back compat.
Since 2.0 we enforce that fields have the same full and index names. So in 3.x
we can remove the ability to have different names on the same field.

Simon Willnauer f5e4cd4616 Remove recovery threadpools and throttle outgoing recoveries on the master
Today we throttle recoveries only for incoming recoveries. Nodes that have a lot
of primaries can get overloaded due to too many recoveries. To still keep that at bay
we limit the number of threads that are sending files to the target to overcome this problem.

The right solution here is to also throttle the outgoing recoveries that are today unbounded on
the master and don't start the recovery until we have enough resources on both source and target nodes.

The concurrency aspects of the recovery source also added a lot of complexity and additional threadpools
that are hard to configure. This commit removes the concurrent streamns notion completely and sends files
in the thread that drives the recovery simplifying the recovery code considerably.
Outgoing recoveries are not throttled on the master via a allocation decider.

Simon Willnauer c3f901400c Move async translog sync logic into IndexService
Today the logic to async - commit the translog is in every translog instance
itself. While the setting is a per index setting we manageing it per shard. This
polluts the translog code and can more easily be managed in IndexService.

Simon Willnauer fcfd98e9e8 Drop support for simple translog and hard-wire buffer to 8kb
Today we have two variants of translogs for indexing. We only recommend the buffered
one which also has a 20% advantage in indexing speed. This commit removes the option and defaults
to the buffered case. It also hard-wires the translog buffer to 8kb instead of 64kb. We used to
adjust that buffer based on if the shard is active or not, this code has also been removed and
instead we just keep an 8kb buffer arround.

Simon Willnauer afc1cc19af Simplify translog-based flush settings
This commit removes `index.translog.flush_threshold_ops` and `index.translog.disable_flush`
in favor of `index.translog.flush_threshold_size`. The number of operations is meaningless by itself and
can easily be turned into a size value with knowledge of the data. Disabling the flush is only useful in
tests and we can set the size value to a really high value. If users really need to do this they can
also apply a very high value like `1PB`.

Robert Muir f67390e0c8 in the plugin: guard against HADOOP_HOME in environment on any platform.
hdfs fixture: minihdfs works on windows now, if things are properly set
but our test fixture still cannot launch this on windows.

Robert Muir 12a8428dfb Add MiniHDFS test fixture, started before integTest and shut down after.
Currently uses a hardcoded port (9999), need to apply MavenFilteringHack after it starts.

Ryan Ernst 9cb4c82c58 Build: Add fixture capabilities to integ tests
This change adds a Fixture class for use by gradle. A Fixture is an
external process that integration tests will use. It can be added as a
dependsOn for integTest, and will automatically be shutdown upon success
or failure, as well as relevant information dumped on failure. There is
also an example fixture in this change.
