command: use consistent CONSUL_HTTP_TOKEN name

nomad: unset consul token on job register

Note that consul-template uses CONSUL_TOKEN, which Nomad also uses,
so be careful to preserve any reference to that in the consul-template
context.

docs: #6065 shipped in v0.10.0, not v0.9.6

PR #6065 was intended to be backported to v0.9.6 to fix issue #6223.
However it appears to have not been backported:

 * https://github.com/hashicorp/nomad/blob/v0.9.6/client/allocrunner/taskrunner/task_runner.go#L1349-L1351
 * https://github.com/hashicorp/nomad/blob/v0.9.7/client/allocrunner/taskrunner/task_runner.go#L1349-L1351

The fix was included in v0.10.0:

 * https://github.com/hashicorp/nomad/blob/v0.10.0/client/allocrunner/taskrunner/task_runner.go#L1363-L1370
