067932aebf resources: Remove SetWatching/IsWatching code from Watch
This removes some boilerplate from the Watch methods which can be baked
into the engine instead.

This code should be checked for races and locks to make sure we only
start resources when it makes sense to.

36b916f27f resources: Simplify resource Converger and Startup code
This takes the Converged initialization and Startup patterns that are
common in all resources, and bakes it into the core engine. This way
resource writing is much more concise and there is less boilerplate!

597ed6eaa0 resources: Polish the password PoC and build out send/recv
This polishes the password resource so that it can actually avoid
writing the password to disk, and so that the work actually happens in
CheckApply where it can properly interact with the graph. This resource
now re-generates the password when it receives a notification.

The send/recv plumbing has been extended so that receivers can detect
when they're receiving new values. This is particularly important if
they might otherwise not expect those values to change and cache them
for efficiency purposes.

b0a8fc165c resources: Improve the state/cache system
Refactor the state cache into the engine. This makes resource writing
less error prone, and paves the way for better notifications.

42ff9b803a resources: Use Events() method instead of raw channel
This makes things easier if we ever split resources out into separate
packages.

b26322fc20 all: Rename UUID to UID.
Felix pointed out that these ID's are unique, but not universally unique
across the cluster, which might be confusing to new programmers. As a
result, rename them all.

ccc00f913d Resources: Update interface to support errors
This was an early interface mistake I made and is now corrected.
We'll plumb in checking the error state of Init() and running Validate()
later on.

63f21952f4 golang: Split things into packages
This makes this logically more separate! :) As an aside...

I really hate the way golang does dependencies and packages. Yes, some
people insist on nesting their code deep into a $GOPATH, which is fine
if you're a google dev and are forced to work this way, but annoying for
the rest of the world. Your code shouldn't need a git commit to switch
to a a different vcs host! Gah I hate this so much.
