[r=rvb][bug=1383231][author=gmb] StaticIPAddressManager._attempt_allocation() now gives a useful error message to the StaticIPAddressUnavailable that it raises when someone is already using a static IP.

Previously, API users were confronted with a blank line when trying to request an in-use IP address.

[r=allenap][bug=1383237][author=gmb] Update the error message returned by the API when trying to reserve an IP on an interface with no static range defined.

Previously, the error claimed there was no such network, but the actual problem is that we exclude interfaces without a static range from our search for networks from which to reserve an IP. The message now suggests that you may be trying to reserve an address on a network with no static range.

[r=julian-edwards][bug=1330765][author=gmb] When it encounters an error, Node.start() now releases any static IP addresses it's claimed. Previously it wouldn't, which meant that the static IPs were unavailable to other nodes.

This branch fixes bug 1330765 (finally!).

[r=allenap][bug=1330765][author=gmb] Remove NodeManager.stop_nodes() and .start_nodes(), and any related tests. This is part of the work toward fixing bug 1330765.

[r=allenap][bug=1330765][author=gmb] Convert call-sites of NodeManager.stop_nodes() to use Node.stop() instead. This is part of the work for fixing bug 1330765.

3277. By Graham Binns on 2014-10-21

[r=julian-edwards][bug=1330765][author=gmb] Convert Node.objects.start_nodes() calls to use Node.start().

I've accounted for all the callsites except those in the tests for start_nodes, which I'll remove in a separate branch.

[r=rvb][bug=1379556][author=julian-edwards] Change the log warning about node events for non-existent nodes to a debug level message. There are *many* of these log messages when a node is enlisting and it's probing for TFTP files, and they are not useful to casual observers.

[r=rvb][bug=1382108][author=julian-edwards] Don't write DHCP host maps when starting a node if its PXE MAC is not on a managed cluster interface, they are not needed. This also removes a related crash (see bug 1382108)
