Rory Hunter 9f069f795c Refactor environment variable processing for Docker (#49612) ... Closes #45223. The current Docker entrypoint script picks up environment variables and translates them into -E command line arguments. However, since any tool executes via `docker exec` doesn't run the entrypoint, it results in a poorer user experience. Therefore, refactor the env var handling so that the -E options are generated in `elasticsearch-env`. These have to be appended to any existing command arguments, since some CLI tools have subcommands and -E arguments must come after the subcommand. Also extract the support for `_FILE` env vars into a separate script, so that it can be called from more than once place (the behaviour is idempotent). Finally, add noop -E handling to CronEvalTool for parity, and support `-E` in MultiCommand before subcommands.		2019-12-16 09:57:18 +00:00
