No function to list the pool in rados.py

No function to list the pool in rados.py

Hi, ceph developments:

  Could we add one more function in rados.py to list the pool?

  I had already implemented the function. Thanks a lot!

class Rados(object):
    def list(self):
        size = c_size_t(512)
        while True:
            c_names = create_string_buffer(size.value)
            ret = self.librados.rados_pool_list(self.cluster,
byref(c_names), size)
            if ret > size.value:
                size = ret
            else:
                break
        return filter(lambda name: name != '', c_names.raw.split('\0'))

Added in c883100448bb7e86b4f0d52a425e0d0a278c79a0 with a couple small 
changes to check that we're connected and keep the type of size c_size_t.

Next time if you could send a patch or github pull request it'd be 
easier to apply.

Thanks!
