If a request hasn't been acknowledged, there's no guarantee for any node to hold the up-to-date cluster state (not even the master yet, as the execution is asynchronous)
The average and sum comparators basically share the same code which is
copy-past today. We can simplify this into a base class which reduces
code duplication and prevents copy-paste bugs.
While testing an async system providing reproducible tests that
use randomized components is a hard task we should at least try to
reestablish the enviroment of a failing test as much as possible.
This commit allows to re-establish the shared 'TestCluster' by
resetting the cluster to a predefined shared state before each test.
Before this commit a tests that is executed in isolation was likely
using a entirely different node enviroment as the failing test since
the 'TestCluster' kept intermediate nodes started by other tests around.
use service id for pid name
disable filtering on *.exe (caused corruption)
rename exe names and add more options to .bat
start/stop operations are now supported (and expected to be called) by service.bat
add more variables from the env to customize default behavior prior to installing the service
add manager option
fixes regarding batch flow
specify service id in description
minor readability improvement
include .exe only in ZIP archive
rename x64 service id to make it work out of the box
add elasticsearch as a service for Windows platforms
based on Apace Commons Daemon
supports both x64 and x86
Compared to setting node.local to true, would be nicer to support node.mode with values of local or network.
Note, node.local is still supported.

The SearchWithRandomExceptionTests aim to catch problems when resources
are not closed due to exceptions etc. Yet in some cases the random seeds
cause the index to never be fully allocated so we basically go into a
ping-pong state where we try to allocate shards back and forth on nodes.
This causes all docs to time out which in-turn causes the tests to run
for a very long time (hours or days).
If we can not allocate the index and get to a yellow state we simply
index only one doc and expected all searches to fail.
This commit also beefs up the assertions in this test to check if
documents are actually present if they are indexed and refresh was
successful.
Closes#3694
Stats can be retrieved on a per-feature / per-component basis including the fields
they apply to. This commit add support for a 'completion' flag to include statistics
for the complition feature as well as 'completion_fields' to only
include certain fields into the returned statistics.
To disambiguate between 'fielddata' and 'completion' fields this commit
uses 'fields' as the default inclusion filter for stats fields only used
if not dedicated '[completion|fielddata]_fields' paramter is provided.
Relates to #3522
