    my $token = $client->delegation_token( get => $path );
    print "Token: $token\n";

    my $milisec = $client->delegation_token( renew => $token );
    printf "Token expiration renewed until %s\n", scalar localtime $milisec / 1000;

    if ( $client->delegation_token( cancel => $token ) ) {
        print "Token cancelled. There will be a new one created.\n";
        my $token_new = $client->delegation_token( get => $path );
        print "New token: $token_new\n";
        printf "New token is %s\n", $token_new eq $token ? 'the same' : 'different';
    }
    else {
        warn "Failed to cancel token $token!";
    }

#### `$client->delegation_token( get => $path, [renewer => $username, service => $service, kind => $kind ] ) :Str )`

Returns the delegation token id for the specified path.

#### `$client->delegation_token( renew => $token ) :Int`
