    Zookeeper 3105:Character coding problem occur when create a node using python3

    when creating a node using python3, InvalidACLException occurs all the time. it`s caused by imcompatible way of parsing acl passed through python3 api.
    so
    
    ```
    acls->data[i].id.id = strdup( PyUnicode_AsUnicode( PyDict_GetItemString( a, "id" ) ) );
    acls->data[i].id.scheme = strdup( PyUnicode_AsUnicode( PyDict_GetItemString( a, "scheme" ) ) );
    ```
    is changed to
    
    ```
    acls->data[i].id.id = strdup( PyBytes_AS_STRING( PyUnicode_AsASCIIString( PyDict_GetItemString( a, "id" ) ) ) );
    acls->data[i].id.scheme = strdup( PyBytes_AS_STRING( PyUnicode_AsASCIIString( PyDict_GetItemString( a, "scheme" ) ) ) );
    ```
    
    because `acls->data[i].id.id` and `acls->data[i].id.scheme` must be an ASCII string.

    i think we can have id be "أليس" and i believe it will get messed up by this code. we need to use UTF-8 encoding. (unfortunately, i'm not familiar enough with python C-bindings to know how to do it correctly...

    i thought the value of id can be "anyone" or ip or the string like "usrname:password", either of them can be represented  as a string. then i tried "anyone", "127.0.0.1/16" and "usrname:password", and they all worked.

    LGTM, it would be great to have test case to cover the coding/decoding part in the python C bind.

    utf-8 encoding is now implemented before passed to a char pointer.

    this only works for ascii strings. that should be ok for scheme, but maybe not for id.
