removed all references to 'distributed_poller_host' as it's not used in any librenms code, and documentation doesn't actually document what it does or is for.
Wait for output on every command, this prevents input left in the buffer from messing up subsequent commands.
It doesn't seem like there is a penalty, but I'd have to do more testing.
