This commit modernizes the qa/acceptance (packaging) test framework by
moving away from Vagrant and having the tests operate locally.
As we are migrating to Buildkite, the expectation is that those tests
will run on dedicated vms thus removing the necessity of vagrant.

Some other minor changes include:
* add back the user level boostrap scripts, useful in that case to pull latest released LS
* cleanup formatting for specs and fixed bootstrap scripts for redhats
* make the latest logstash version available from the current platform config file
* make sure debian based machines use java8
* make sure to use hostname and not just ip:port address when reporting the names
Fixes#5350
Also:
* Refactored the specs organization to make the resoning behind simplier,
introducing the idea of an artifact subject that it wraps the
interactions with the platform.
* Add methods to destroy, bootstrap and halt a list of machines either all of them or the ones listed under a given platform name.
* Introduced more clear namespacing in the rakefile.
* Updated the list of available platforms for acceptance testing, including latest ubuntu, oel, fedora, debian and suse versions
Fixes#5350
This change introduce a new command ci/ci_acceptance which is
responsable of building the packages, bootstraping the acceptance test
environment, launching the VMs and running the tests.
You can use the following command to target specific platform.
```
ci/ci_acceptance.sh all
ci/ci_acceptance.sh centos
ci/ci_acceptance.sh debian
```
This PR also add a new rake task to build all the artifacts in a single
run called rake artifact:all it make sure we only install the plugin
only once and make the build process faster.
Fixes#5350
