Title: fix populate for single int

Latest commit failed to parse single int for -n option. I got following error.

```
Traceback (most recent call last):
File "/Users/yuki/Developments/bin/ccm", line 66, in
cmd.validate(parser, options, args)
File "/Users/yuki/Developments/tools/ccm/ccmlib/cmds/cluster_cmds.py", line 62, in validate
self.nodes = parse_populate_count(options.nodes)
File "/Users/yuki/Developments/tools/ccm/ccmlib/cmds/cluster_cmds.py", line 35, in parse_populate_count
return int(tmp)
TypeError: int() argument must be a string or a number, not 'list'
```

Simple fix for above.
