Wrong handler in sensu plugin file

Issue

• There is one custom plugin in Sensu, check-docker-health, that has a different handler configured than the rest of the Sensu alarms.

• This is the default file (see that it has no handler defined):

[root@overcloud-compute-0 checks]# cat check-docker-health.json 
{
    "checks": {
        "check-docker-health": {
            "command": "output=''\nfor i in $(docker ps --format '{{.ID}}'); do\n  if result=$(docker inspect --format='{{.State.Health.Status}}' $i 2>/dev/null); then\n    if [ \"$result\" != 'healthy' ]; then\n      output=\"${output} ; $(docker inspect --format='{{.Name}}' $i) ($i): $(docker inspect --format='{{(index .State.Health.Log 0).Output}}' $i)\";\n    fi\n  fi\ndone\nif [ ! -z \"${output}\" ]; then\n  echo ${output:3} && exit 2;\nfi\n",
            "handlers": [

            ],
            "interval": 10,
            "occurrences": 3,
            "refresh": 90,
            "standalone": true
        }
    }
}

• This is how it should look like:

[root@overcloud-compute-1 checks]# cat check-docker-health.json 
{
    "checks": {
        "check-docker-health": {
            "command": "output=''\nfor i in $(docker ps --format '{{.ID}}'); do\n  if result=$(docker inspect --format='{{.State.Health.Status}}' $i 2>/dev/null); then\n    if [ \"$result\" != 'healthy' ]; then\n      output=\"${output} ; $(docker inspect --format='{{.Name}}' $i) ($i): $(docker inspect --format='{{(index .State.Health.Log 0).Output}}' $i)\";\n    fi\n  fi\ndone\nif [ ! -z \"${output}\" ]; then\n  echo ${output:3} && exit 2;\nfi\n",
            "handlers": [
                "default"
            ],
            "interval": 10,
            "occurrences": 3,
            "refresh": 90,
            "standalone": true
        }
    }
}
