consul/connect: Validate uniqueness of Connect upstreams within task group

This PR adds validation during job submission that Connect proxy upstreams
within a task group are using different listener addresses. Otherwise, a
duplicate envoy listener will be created and not be able to bind.

Closes #7833

e2e: fix a couple recent e2e bugs

This PR changes the e2e helper thingy to set -detach option
when registering a job with the CLI instead of the API. This is
necessary for jobs which never become healthy, as the deployment
never finishes for failing jobs and the command never returns,
causing the test to timeout after 10 minutes.
