add an N|Solid tag for cf org, as is done for cf space about nsolid-buildpack-cf-v2

[pmuellr]

We currently get the tags we add from the env var VCAP_APPLICATION, which has the following interesting properties:

{
    "application_id": "[uuid-here]",
    "application_name": "pjm-hello-world",
    "application_version": "[uuid-here]",
    "cf_api": "https://api.run.pivotal.io",
    "instance_id": "[uuid-here]",
    "space_id": "[uuid-here]",
    "space_name": "development"
}

So ... no info on the org is directly available from VCAP_APPLICATION. Poking around other env vars, didn't see anything there either.

Curious as to why org_id and org_name aren't listed here ... should bubble this back up through the Cloud Foundry org.

The relevant org data COULD be obtained indirectly, by interacting with the cloud controller directly, or via cf, but ... that would require full login credentials to be able to get the info, which doesn't seem like a safe thing to do.

Other alternatives would be to automagically add the org name at deployment time, via deployment scripts / manifests / tooling, which would seed the NSOLID_TAGS env var with the calculated tag.

closing as there's not much we can do in the buildpack itself
