[Docs] logstash-jdbc-static requires local_table

Brief:

The docs on elastic.co are incorrect. while the examples contains the correct information, the plugin detail does not.

Specifically under loaders, table should be updated to local_table https://www.elastic.co/guide/en/logstash/6.7/plugins-filters-jdbc_static.html#plugins-filters-jdbc_static-loaders

    id => "local-servers"
    query => "select descr as description from servers WHERE ip = :ip"
