Daniel Nephin ef0999547a testing: skip slow tests with -short
Add a skip condition to all tests slower than 100ms.

This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests

With this change:

```
$ time go test -count=1 -short ./agent
ok      github.com/hashicorp/consul/agent       0.743s

real    0m4.791s

$ time go test -count=1 -short ./agent/consul
ok      github.com/hashicorp/consul/agent/consul        4.229s

Daniel Nephin e4a78c977d stream: document that Payload must be immutable
If they are sent to EventPublisher.Publish.

Also document that PayloadEvents is expected to come from a subscription and that it is
not immutable.

Daniel Nephin 61ce0964a4 stream: remove Event.Key
Makes Payload a type with FilterByKey so that Payloads can implement
filtering by key. With this approach we don't need to expose a Namespace
field on Event, and we don't need to invest micro formats or require a
bunch of code to be aware of exactly how the key field is encoded.

Daniel Nephin a2f8605c66 stream: Add forceClose and refactor subscription filtering
Move the subscription context to Next. context.Context should generally
never be stored in a struct because it makes that struct only valid
while the context is valid. This is rarely obvious from the caller.
Adds a forceClosed channel in place of the old context, and uses the new
context as a way for the caller to stop the Subscription blocking.

Remove some recursion out of bufferImte.Next. The caller is already looping so we can continue
in that loop instead of recursing. This ensures currentItem is updated immediately (which probably
does not matter in practice), and also removes the chance that we overflow the stack.

NextNoBlock and FollowAfter do not need to handle bufferItem.Err, the caller already
handles it.

Moves filter to a method to simplify Next, and more explicitly separate filtering from looping.

Also improve some godoc

Only unwrap itemBuffer.Err when necessary

Daniel Nephin 16a2b3fafc stream: change Topic to an interface
Consumers of the package can decide on which type to use for the Topic. In the future we may
use a gRPC type for the topic.

Daniel Nephin 02bc5a26e4 EventPublisher: Make Unsubscribe a function on Subscription
It is critical that Unsubscribe be called with the same pointer to a
SubscriptionRequest that was used to create the Subscription. The
docstring made that clear, but it sill allowed a caler to get it wrong by
creating a new SubscriptionRequest.

By hiding this detail from the caller, and only exposing an Unsubscribe
method, it should be impossible to fail to Unsubscribe.

Also update some godoc strings.
