tracking: Equinix open source program support

[vielmetti]

This is a tracking item to coordinate efforts around access to Equinix Metal resources, per an application to our open source program by @dtaht .

Some possible goals include access to the platform by the team, automation to support testing, performance characterization and tuning, NIC card support, and the like. We'll also be interested in communicating results, both internally and externally.

I'm tasked with establishing a budget for this, so that we can keep tabs on usage. This is mostly about identifying needs and figuring out the effective way to fulfill them, rather than establishing some arbitrary dollar target.

more to follow
