update github.com/satori/go.uuid to 1.2.0

**What this PR does / why we need it**:

This makes sure that github.com/Azure/azure-sdk-for-go has the dependency it
requires: as of v14.6.0, it has a constraint for github.com/satori/go.uuid to be
at 1.2.0 (or above).
This was introduced in https://github.com/Azure/azure-sdk-for-go/pull/979
(see discussion for rationale)

Since github.com/Azure/azure-sdk-for-go is the only consumer of
github.com/satori/go.uuid, there is no reason not to use the correct version.

This also prepares the ground for a future migration to dep.

Fixed detection of inaccessible AWS encryption key.

AWS provisioner now checks if created encrypted volume gets "Available" or it gets silently deleted by AWS because StorageClass referenced invalid (e.g. non-existing) KMS key for encryption.

This seems to be the only way how to detect such invalid key, because Kubernetes may not have enough permission to check if the key exists.

Remove optimization from getWork in resourcequota/controller.go

**What this PR does / why we need it**:
This change simplifies the code in

completeWork if getWork returns the empty list of work.  BTW, the
caller was not obeying that requirement; now the caller's behavior
(which is unchanged) is right.
