Pass environment variable to check script

[Xeite]

Feature Description

Currently as far as I know, there is no way to pass shell environment variable to check script. I think if we can pass the necessary variables to check, user can maintain their check configuration cleaner.

Use Case(s)

I have to add bash command for my check script which use OpenStack environment (OS_AUTH_URL...) to avoid the limitation that I said.

If the requested feature added, I can change my configuration

AS-IS

"check": {
      "name": "Check routing table",
      "interval": "10s",
      "args": [
        "/bin/bash",
        "-c",
        "source /etc/consul/conf.d/openrc_v3; /opt/sanitychecker/bin/sanitychecker route"
      ]
}

TO-BE

"check": {
      "name": "Check routing table",
      "interval": "10s",
      "args": [
           "/opt/sanitychecker/bin/sanitychecker", "route"
      ]
     "environments": [
        OS_SERVICE_TOKEN=...
        OS_SERVICE_ENDPOINT=...
        OS_TENANT_NAME=...
        OS_USERNAME=...
        OS_PASSWORD=...
        OS_AUTH_URL=...
      ]
}

Thanks!

A step better even would be if the value side of the env assignment could be a reference to a value stored in consul.

an environmentFile option would also be good.
