This commit moves away from using stripe RAID-0 simumlation across multiple
data paths towards using a single path per shard. Multiple data paths are still
supported but shards and it's data is not striped across multiple paths / disks.
This will for instance prevent to loose all shards if a single disk is corrupted.
Indices that are using this features already will automatically upgraded to a single
datapath based on a simple diskspace based heuristic. In general there must be enough
diskspace to move a single shard at any time otherwise the upgrade will fail.
Closes#9498
The existing DEB/RPM packages have a lot of differences: they don't execute the same actions when installing or removing the package. They also don't declare exactly the same environment variables at the same place. At the end of the day the global behavior and configuration is *almost* the same but it's very difficult to maintain the scripts.
This commits unifies the package behavior:
- DEB/RPM use the same package scripts (pre installation, post installation etc) in order to execute exactly the same actions
- Use of a unique environment vars file that declares everything needed by scripts (the goal is to delete vars declaration in init.d and systemd scripts, this will be done in another PR)
- Variables like directory paths are centralized and replaced according to the target platform (using #10330)
- Move /etc/rc.d/init.d to standard /etc/init.d (RPM only)
- Add PID_DIR env var
- Always set ES_USER, ES_GROUP,MAX_MAP_COUNT and MAX_OPEN_FILES in env vars file
- Create log, data, work and plugins directories with DEB/RPM packaging system
- Change to elastic.co domain in copyright and control files
- Add Bats files to automate testing of DEB and RPM packages
- Update TESTING.asciidoc

Now that we handle automatically the local execution within the transport service, we can remove parts of the code that handle it in actions.
