File watcher synonym for ElasticSearch

The file watcher synonym plugin adds a synonym token filter that reloads the synonym file at given intervals (default 60s).

Example:

{
    "index" : {
        "analysis" : {
            "analyzer" : {
                "synonym" : {
                    "tokenizer" : "whitespace",
                    "filter" : ["synonym"]
               }
            },
            "filter" : {
                "synonym" : {
                    "type" : "file_watcher_synonym",
                    "synonyms_path" : "analysis/synonym.txt"
                    "interval" : "10s"
                }
            }
        }
    }
}
