Tanguy Leroux 168238dab6 Add properties files to configure startup and installation scripts
Many scripts are used to start/stop and install/uninstall elasticsearch. These scripts share a lot of configuration properties like directory paths, max value for a setting, default user etc. Most of the values are identical but some of them are different depending of the platform (Debian-based or Redhat-based OS), depending of the way elasticsearch is started (shell script, systemd, sysv-init...) or the way it is installed (zip, rpm, deb...). Today the values are duplicated in multiple places, making it difficult to maintain the scripts or to update a value.

This pull request make this more uniform: values used in scripts must be defined in a common packaging.properties file. Each value can be overridden in another specific packaging.properties file for Debian or Redhat. All startup and installation scripts are filtered with the common then the custom packaging.properties files before being packaged as a zip/tar.gz/rpm/dpkf archive.
