Issue

On a placement failure status returned is "complete" in evaluation structure.
There's no error the only thing one can use to detect this is 'trigger-by' field where i have will have to compare to string "job-deregister"

i understand since evaluation is complete(concluded job cannot be placed) so status is complete , but there i don't see a simple way to find out if job got placed

Reproduction steps

added a sample job file

Expected Result

expecting EvalStatus to be blocked or cancelled

Actual Result

Job file (if appropriate)

job "docs" {
  datacenters = ["hz1"]

  group "example" {
    network {
      port "http" {
        static = 5678
      }
    }

    task "server" {
      driver = "docker"
      constraint {
        attribute = "${meta.my_custom_value}"
        operator  = ">"
        value     = "3"
      }
      config {
        image = "hashicorp/http-echo"
        ports = ["http"]
        args = [
          "-listen",
          ":5678",
          "-text",
          "hello world"
        ]
