What does this PR do?

Adds a file:// endpoint to the profile exporter.

Motivation

For testing and debugging purposes, its really useful to see exactly what bytes were sent. This is useful both within libdatadog, and also for any clients.

Additional Notes

Anything else we should know when reviewing?

How to test the change?

New integration tests in the PR.
