Nomad does not mark deployment as successful with dynamic service names

[Blefish]

Nomad version

Output from nomad version
Nomad v1.4.5, v1.5.0

Operating system and Environment details

Linux Mint 21.1

Issue

Services with dynamic names never report healthy deployment status, although services are healthy in Consul view. Seems to be occuring after #15822 , could it be that dynamic service name is not being evaluated before validating the service checks?

Reproduction steps

Expected Result

Service healthiness result from Consul is forwarded to Nomad and deployment is successful.

Actual Result

Service healthiness is not received by Nomad and deployment is marked as failed after a while.

Job file (if appropriate)

A service which uses custom name that is dynamically evaluated (NOMAD_GROUP_NAME, NOMAD_JOB_NAME or similar)

service {
  name = "${NOMAD_JOB_NAME}"
  port = "grpc"
  check {
    type = "grpc"
    interval = "10s"
    timeout = "5s"
    check_restart {
      limit = 3
      grace = "90s"
      ignore_warnings = false
    }
  }
}

Thanks for the report @Blefish, your analysis was correct and there was a bug in #15822 where were not interpolating service values. I opened #16402 to fix this.
