Depending on how elasticsearch is installed, we have two scenarios to take into account that relate to user, group and permissions assigned to the config directory:
1) deb/rpm package: /etc/elasticsearch is root:elasticsearch 750 and the plugin script is run from root user
2) tar/zip archive: es config dir is most likely elasticsearch:elasticsearch and the plugin script is most likely run from elasticsearch user
When the plugin script copies over the plugin config dir within the es config dir, it should take care of setting the proper user, group and permissions, which vary depending on how elasticsearch was installed in the first place. Should be root:elasticsearch 750 if installed from a package, or elasticsearch:elasticsearch if installed from an archive.
This commit makes sure that the plugin script looks at user, group and permissions of the config dir and copies them over to the plugin config subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed in the first place. We also make sure that execute permissions are left untouched for files.
