* Explicitly point out the JDK 8 requirement is for runtime, but not for compiling.
* Clarify the JAVAx_HOME env variables are for the "backwards compatibility test".
* Add explanation on how the backwards compatibility tests get the OpenSearch distributions for a specific version.

* Lower build requirement from Java 14+ to Java 11+
Avoid use of -Werror -Xlint:all, which may change significantly across
java releases (new warnings could be added). Instead, just list the
warnings individually.
Workaround JDK 11 compiler bug (JDK-8209058) that only impacts test fixture
code in the build itself.

* Disable warning around -source 7 -release 7 for java version checker
The java version checker triggers some default warnings because it
targets java7:
```
> Task :distribution:tools:java-version-checker:compileJava FAILED
warning: [options] source value 7 is obsolete and will be removed in a future release
warning: [options] target value 7 is obsolete and will be removed in a future release
warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.
error: warnings found and -Werror specified
```
Suppress this warning explicitly for this module.

OpenSearch uses plugins to add new features. A plugin can be included in the distribution by default (as part of *modules* directory) or can be installed optionally from a plugin repository.
This change provides a separate space called *sandbox* inside OpenSearch for the community to easily experiment new ideas and innovate. Ideally, this is where an experimental feature will reside before it can be promoted to the *modules* directory. All the plugins in this module will only be included in the **snapshot distributions**. During assembling distributions, we will check if the following two conditions are met to include the sandbox modules,
* the distribution is a snapshot i.e. the build system property `build.snapshot` is set to true. We use this because it will prevent accidental bundling of these modules in a release distribution.
* the `enable.sandbox` system property is set to true. By default it is set to true. The purpose of adding this extra flag is that we can exclude the modules from snapshots if needed. For example, we may want to run performance tests on snapshots without the sandbox modules.
