Signed-off-by: John Howard <jhoward@microsoft.com>

This also adds go.etcd.io/bbolt as boltdb/bolt is no longer
maintained, and we need https://github.com/etcd-io/bbolt/pull/122 which
was merged in https://github.com/etcd-io/bbolt/releases/tag/v1.3.1-etcd.8
in order to fix https://github.com/docker/libnetwork/issues/1950.

Note that I can't entirely remove boltdb/bolt as it is still used by
other components. Still need to work my way through them.... These include
containerd/containerd (https://github.com/containerd/containerd/pull/2634),
docker/swarmkit; moby/buildkit. And probably more....
