feat(api): avoid AL if it's not an AL on /mon/status

[yesnault]

example (default min is 1 for everything):

  [api.status]

    [api.status.api]

      # if less than minInstance of API is running, an alert will on Global/API be created on /mon/status
      minInstance = 1

    [api.status.dbmigrate]

      # if less than minInstance of dbmigrate service is running, an alert on Global/dbmigrate will be created on /mon/status
      minInstance = 0

    [api.status.elasticsearch]

      # if less than minInstance of elasticsearch service is running, an alert on Global/elasticsearch will be created on /mon/status
      minInstance = 0

    [api.status.hatchery]

      # if less than minInstance of hatchery service is running, an alert on Global/hatchery will be created on /mon/status
      minInstance = 1

    [api.status.hooks]

      # if less than minInstance of hooks service is running, an alert on Global/hooks will be created on /mon/status
      minInstance = 1

    [api.status.repositories]

      # if less than minInstance of repositories service is running, an alert on Global/hooks will be created on /mon/status
      minInstance = 0

    [api.status.vcs]

      # if less than minInstance of vcs service is running, an alert will on Global/vcs be created on /mon/status
      minInstance = 1
