Wrong type for "--count" arg

[bioex]

The "--count" argument does not really work:

# python /var/tmp/bind-query-log-stats.py --count 10 /var/log/dns/query.log
Processing logfile /var/log/dns/query.log

<skip>

Top  ['10']  DNS names requested:
Traceback (most recent call last):
  File "/var/tmp/bind-query-log-stats.py", line 265, in <module>

    for query, _ in Counter(DNS_QUERIES).most_common(num_print):
  File "/usr/lib64/python2.7/collections.py", line 462, in most_common
    return _heapq.nlargest(n, self.iteritems(), key=_itemgetter(1))
  File "/usr/lib64/python2.7/heapq.py", line 465, in nlargest
    result = _nlargest(n, it)
TypeError: an integer is required

@bioex remove nargs=1, from the line below and add type=int

parser.add_argument('--count', help="Number of entries to display",
                    default=100, type=int, metavar="Count")
