Also, since github.com/docker/docker is the canonical package names and
is transparently forwarded to github.com/moby/moby, I removed the
moby/moby references in origin.
Issue #7523 documents the Consul ACLs used in each Consul interface
used by Nomad. Minimize the policies used in e2e tests so that we
are setting a good example.
The `csi_plugins` and `csi_volumes` tables were missing support for
snapshot persist and restore. This means restoring a snapshot would
result in missing information for CSI.
In tests where the logger is a test logger, emitting a trace log in a
background thread while it's shutting down may trigger a panic. Thus
avoid logging Trace if err != nil. Note that we already log an error
when err isn't a trace.
This fixes cases where tests panic with a trace like:
```
panic: Log in goroutine after TestAllocGarbageCollector_MakeRoomFor_MaxAllocs has completed

The test inserts an alloc in the server state, but expect the client to
start the alloc runner for it almost immediately.
Here, we add a retry loop to check that the client start all expected
alloc runners eventually.

* added method to retrieve all scaling policies for use in snapshotting, plus test
* better testing for ScalingPoliciesByNamespace
* added scaling policy snapshot persist and restore (and test of restore)
manually tested snapshot restore.
resolves#7539
Looks like the latest `github.com/docker/docker/registry.ResolveAuthConfig` expect
`github.com/docker/docker/api/types.AuthConfig` rather than
`github.com/docker/cli/cli/config/types.AuthConfig`. The two types are
identical but live in different packages.
Here, we embed `registry.ResolveAuthConfig` from upstream repo, but with
the signature we need.
links ending with / and links without a terminal / are handled the same
according to the netlify redirect documenation
