[Spike] Super Agent Health Check

[kmudduluru]

Our first task in supporting the SuperAgent is having the Node.js Agent periodically write out a “health” check, as described in this spec

Some key points in looking for a solution:

The code should do nothing unless the environment variable is set with a valid location

If we already have any health reporting modules in the agent (reuse if any available).

Reach out in #apm-agent-fm-super-agent channel for any questions.

.net agent spike ticket - https://new-relic.atlassian.net/issues/NR-335857 for reference.

Goal is to create a backlog of tickets and any design doc to implement this feature in Node
