Spike Curtis 42324b386a chore: add clock pkg for testing time (#13461)
Adds a package for testing time/timer/ticker functions.  Implementation is limited to `NewTimer` and `NewContextTicker`, but will eventually be expanded to all `time` functions from the standard library as well as `context.WithTimeout()`, `context.WithDeadline()`.

Replaces `benbjohnson/clock` for the pubsub watchdog, as a proof of concept.

Eventually, as we expand functionality, we will replace most time-related functions with this library for testing.

// Package clock is a library for testing time related code. It exports an interface Clock that
// mimics the standard library time package functions. In production, an implementation that calls
// thru to the standard library is used. In testing, a Mock clock is used to precisely control and
// intercept time functions.
package clock
import (
"context"
"time"
)
type Clock interface {
// TickerFunc is a convenience function that calls f on the interval d until either the given
// context expires or f returns an error. Callers may call Wait() on the returned Waiter to
// wait until this happens and obtain the error.
TickerFunc(ctx context.Context, d time.Duration, f func() error, tags ...string) Waiter
// NewTimer creates a new Timer that will send the current time on its channel after at least
// duration d.
NewTimer(d time.Duration, tags ...string) *Timer
}
// Waiter can be waited on for an error.
