This update provides:
1) workaround around the build failures. In
summary, it forces the download of some packages during the build
process.
2) update the set of packages that should go inside the vendor
directory
3) Update the dockerfile to use go 1.10

+clockwork
+=========
+
+[](https://travis-ci.org/jonboulle/clockwork)
+[](http://godoc.org/github.com/jonboulle/clockwork)
+
+a simple fake clock for golang
+
+# Usage
+
+Replace uses of the `time` package with the `clockwork.Clock` interface instead.
+
+For example, instead of using `time.Sleep` directly:
+
+```
+func my_func() {
+ time.Sleep(3 * time.Second)
+ do_something()
+}
+```
+
+inject a clock and use its `Sleep` method instead:
+
+```
+func my_func(clock clockwork.Clock) {
+ clock.Sleep(3 * time.Second)
+ do_something()
+}
+```
+
+Now you can easily test `my_func` with a `FakeClock`:
+
+```
+func TestMyFunc(t *testing.T) {
+ c := clockwork.NewFakeClock()
+
+ // Start our sleepy function
+ my_func(c)
+
+ // Ensure we wait until my_func is sleeping
+ c.BlockUntil(1)
+
+ assert_state()
+
+ // Advance the FakeClock forward in time
+ c.Advance(3)
+
+ assert_state()
+}
+```
+
+and in production builds, simply inject the real clock instead:
+```
+my_func(clockwork.NewRealClock())
+```
+
+See [example_test.go](example_test.go) for a full example.
+
+# Credits
+
+clockwork is inspired by @wickman's [threaded fake clock](https://gist.github.com/wickman/3840816), and the [Golang playground](http://blog.golang.org/playground#Faking time)
