Restore ability to run nodepoold with fakes With OSC and shade patches, we lost the ability to run nodepoold in the foreground with fakes. This restores that ability. The shade integration unit tests are updated to use the string 'real' rather than 'fake' in config files, as they are trying to avoid actually using the nodepool fakes, and the use of the string 'fake' is what triggers their use in many cases.

Use a sensible SQLAlchemy session model The existing db session strategy was inherited from a bunch of shell scripts that ran once in a single thread and exited. The surprising thing is that even worked at all. This change replaces that "strategy" with one where each thread clearly begins a new session as a context manager and passes that around to functions that need the DB. A thread-local session is used for convenience and extra safety. This also adds a fake provider that will produce fake images and servers quickly without needing a real nova or jenkins. This was used to develop the database change. Also some minor logging changes and very brief developer docs. Change-Id: I45e6564cb061f81d79c47a31e17f5d85cd1d9306

Add 'labels' as a configuration primitive Labels replace images as the basic identity for nodes. Rather than having nodes of a particular image, we now have nodes of a particular label. A label describes how a node is created from an image, which providers can supply such nodes, and how many should be kept ready. This makes configuration simpler (by not specifying which images are associated with which targets and simply assuming an even distribution, the target section is _much_ smaller and _much_ less repetitive). It also facilitates describing how a nodes of potentially different configurations (e.g., number of subnodes) can be created from the same image. Change-Id: I35b80d6420676d405439cbeca49f4b0a6f8d3822

Move the fakeprovider module to the fake driver This change is a follow-up to the drivers spec and it makes the fake provider a real driver. The fakeprovider module is merged into the fake provider and the get_one_cloud config loader is simplified. Change-Id: I3f8ae12ea888e7c2a13f246ea5f85d4a809e8c8d

Add ability to select flavor by name or id It's possible that it's easier for a nodepool user to just specify a name or id of a flavor in their config instead of the combo of min-ram and name-filter. In order to not have two name related items, and also to not have the pure flavor-name case use a term called "name-filter" - change name-filter to flavor-name, and introduce the semantics that if flavor-name is given by itself, it will look for an exact match on flavor name or id, and if it's given with min-ram it will behave as name-filter did already.
