Remove "init_timeout" in RemoteFileClient.get_file

This timeout seems to attempt to retry in the event that the master returns nothing-- but the channel should be responsible for that.

In addition this would retry infinitely since the retry counter was re-initialized on every loop iteration. This meant you spun with an strace that looks something like:

```

Lastly, this retry attempt counter did nothing in the event of 10 failures (assuming it could get one) so it should be safe to remove it all together
