If there is a failure in the elasticsearch start script, we currently
completely lose the failure. This is due to how spawning works with ant.
This change avoids the issue by introducing an intermediate script,
built dynamically before running ant exec, which runs elasticsearch and
redirects the output to a log file. This essentially causes us to run
elasticsearch in the foreground and capture the output, but at the same
time keep a running script which ant can pump streams from (which will
always be empty).
Sometimes when running elasticsearch, it is useful to attach a remote
debugger. This change adds a --debug-jvm option (the same name gradle
uses for its tests debug option), which adds java agent config for a
remote debugger. The configuration is set to hava java suspend until the
remove debugger is attached.

We recently got a run command with gradle, but it is sometimes useful to
run ES with a specific plugin. This is a start, by making each esplugin
have a run command which installs the plugin and runs elasticsearch in
the foreground.
With gradle, deploying to maven means first generating poms. These are
filled in based on dependencies of the project. Recently, we started
disallowing transitive dependencies. However, this configuration does
not translate to maven poms because maven has no concept of excluding
all transitive dependencies.
This change adds exclusions for each of the transitive deps of each
dependency being added to the maven pom. It does so by creating dummy
configurations for each direct dependency (which does not have
transitive deps excluded), so that we can iterate the transitive deps
when building the pom.
Note, this should be simpler (just modifying maven's pom model), but
gradle tries to hide that from their api, causing us to need to
manipulate the xml directly.

If we use JAVA_HOME consistently for tests, we can run tests with a
different version of java than gradle runs with. For example, this
enables running tests with jigsaw, but building with java 8. The only
caveat is intellij does not set JAVA_HOME. This change enforces
JAVA_HOME is set, but ignores for intellij.
This moves the min java version used by elasticsearch to one place, a
constant in BuildPlugin. For me on java 9, this fixed my jar to have the
correct target/source versions.

Transitive dependencies can be confusing and hard to deal with when
conflicts arise between them. This change removes transitive
dependencies from elasticsearch, and forces any dependency conflicts to
be resolved manually, instead of automatically by gradle.
closes#14627
Some dependencies must be specified in a couple places in the build.
e.g. randomized runner is specified both in buildSrc (for the gradle
wrapper plugin), as well as in the test-framework.
This change creates buildSrc/versions.properties which acts similar to
the set of shared version properties we used to have in the maven parent
pom.
run.sh and run.bat were calling out to the old maven build system.
This is no longer in place, so we've created new gradle tasks to
start an elasticsearch node from the current codebase.

This makes it a groovy project that works in eclipse.
You will have to install a plugin for groovy language support
(I used a snapshot build from https://github.com/groovy/groovy-eclipse/wiki)
Eclipse does not have the ability to differentiate test dependencies
from main dependencies. This causes what looks like a circular
dependency through test-framework. This change sets up an additional
core-tests project for eclipse only, which removes this problem.
This adds a generated-resources dir that the plugin properties are
generated into. This must be outside of the build dir, since intellij
has build as "excluded".
