Periodically performs the tensorflow op in body.

The body tensorflow op will be executed every period times the periodically op is executed. More specifically, with n the number of times the op has been executed, the body will be executed when n is a non zero positive multiple of period (i.e. there exist an integer k > 0 such that k * period == n).

If period is None, it will not perform any op and will return a tf.no_op().

If period is 1, it will just execute the body, and not create any counters or conditionals.
