* Docker integration tests stability improvements
This commit contains numerous fixes to improve the stability of the docker integration tests
* Patch Excon::UnixSocket
Socket.new running on arm64 on Ubuntu 18.04, causes an immediate SIGSEGV error and crash on
that OS, and, as far as I can tell, only that OS. `TCPSocket.new`,`UDPSocket.new` and
`UNIXSocket.new` do not. This commit patches the UnixSocket of the Excon library to
do the absolute simplest thing possible to avoid this error.
* Ensure that container is deleted even if #kill fails
* Add extra waits to handle the incremental way the payload returned by the monitoring
API increases as logstash starts up and pipelines load.
* Use pyenv to ensure the same version of python is used across different jenkins workers
* Add container logs to help diagnose failed test.
* Update the pipeline definition on multi-pipeline integration test
This was causing a pipeline to halt after startup causing intermittent test failures.
* Remove `;` to ensure failures are propagated appropriately

* Introduce integration tests for docker
This commit adds integration tests for the Logstash docker images. Previous
integration tests were removed in https://github.com/elastic/logstash/pull/10693,
due to the tests being non functional.
The commit adds image and container tests. The image tests check the contents and the
metadata of the image; the container tests check the logstash process, and includes tests
ensuring that logstash runs, and is configurable.
This test also adds a ci script to allow the tests to be run on jenkins, and to split the
running of these tests up based on the image type and includes updates to the rake tasks to
support this.
