"perform_request()"

    $request = $client->parse_request(\%defn,\%params);

The %defn is a definition returned by "api()" in Search::Elasticsearch::Role::API with an extra key "name" which should be the name of the method that was called on the client. For instance if the user calls "$client->search", then the "name" should be "search".

"parse_request()" will turn the parameters that have been passed in into a "path" (via "path_init()" in Search::Elasticsearch::Util::API::Path), a query-string hash (via "qs_init" in Search::Elasticsearch::Util::API::QS) and will through a "body" value directly.

NOTE: If a "path" key is specified in the %params then it will be used directly, instead of trying to build path from the path template. Similarly, if a "params" key is specified in the %params, then it will be used as a basis for the query string hash. For instance:

    $client->perform_request(
        {
            method => 'GET',
            name   => 'new_method'
        },
        {
            path   => '/new/method',
            params => { foo => 'bar' },
            body   => \%body
        }
    );

This makes it easy to add support for custom plugins or new functionality not yet supported by the released client.
