Custom mysql port and timeout integer fix

When mysql.pyconf configured with custom port:

    param port {
      value = 3307
    }

gmond gives into log:
[PYTHON] Can't call the metric_init function in the python module [mysql].#012

and further investigation with
*gmond -d 1*
shows

[PYTHON] Can't call the metric_init function in the python module [mysql].
Traceback (most recent call last):

Method params.get converted explicitly as integer with timeout and port option.
