 # This define allows you to install arbitrary Elasticsearch plugins
 # either by using the default repositories or by specifying an URL
 #
 # @example install from official repository
 #   elasticsearch::plugin {'mobz/elasticsearch-head': module_dir => 'head'}
 #
 # @example installation using a custom URL
 #   elasticsearch::plugin { 'elasticsearch-jetty':
 #    module_dir => 'elasticsearch-jetty',
 #    url        => 'https://oss-es-plugins.s3.amazonaws.com/elasticsearch-jetty/elasticsearch-jetty-0.90.0.zip',
 #   }
 #
 # @param ensure
 #   Whether the plugin will be installed or removed.
 #   Set to 'absent' to ensure a plugin is not installed
 #
 # @param configdir
 #   Path to the elasticsearch configuration directory (ES_PATH_CONF)
 #   to which the plugin should be installed.
 #
 # @param java_opts
 #   Array of Java options to be passed to `ES_JAVA_OPTS`
 #
 # @param java_home
 #   Path to JAVA_HOME, if Java is installed in a non-standard location.
 #
 # @param module_dir
 #   Directory name where the module has been installed
 #   This is automatically generated based on the module name
 #   Specify a value here to override the auto generated value
 #
 # @param proxy_host
 #   Proxy host to use when installing the plugin
 #
 # @param proxy_password
 #   Proxy auth password to use when installing the plugin
 #
 # @param proxy_port
 #   Proxy port to use when installing the plugin
 #
 # @param proxy_username
 #   Proxy auth username to use when installing the plugin
 #
 # @param source
 #   Specify the source of the plugin.
