Declarative Cache Control API

[JakeWharton]

I've been sitting on this for a while as a future feature but hadn't documented it.

The API would allow specifying a cache interaction policy both "downward" on the load and "upward" back through the processing. Through this you can facilitate complex cache interactions for both valid and seemingly-questionable use cases.

Random subset of interactions from other issues:

• Skip memory cache "downward" only.
• Skip memory cache "upward" only.
• Load from local cache (memory or disk) only.
• Force re-load from network.

I'm not going to do a full-on API strawman, but I know we'll probably want some EnumSet action with

public enum BitmapSource { MEMORY, DISK, NETWORK }
public enum BitmapSink { MEMORY, DISK }

This API will trump the existing weak skipCache() method on RequestCreator.
