* apiserver/storage/continue: intro PrepareContinueToken
PrepareContinueToken prepares optional
parameters for retrieving additional results for a paginated request.
This function sets up parameters that a client can use to fetch the remaining results
from the server if they are available.
* apiserver/storage/etcd3: refactor to use PrepareContinueToken

Our tests are mostly error based and explicit error typing allows
us to test against error types directly. Having made this change also
makes it obvious that our test coverage was lacking in two branches,
specifically, we were previously not testing empty start keys nor were
we testing for invalid start RVs.

The means by which we encode and decode the continue token during a
paginated LIST call is not specific to etcd3. In order to allow for a
generic suite of tests against any storage.Interface implementation, we
need this logic to live outside of the etcd3 package, or import cycles
will exist.
