RFC: Remote Compilation

[Hoverbear]

Not everyone is happy about having a development toolchain on their database machine.

PL/Rust should support some sort of remote compilation facility.

• PL/Rust should have some GUC defining between local or remote builds, and not require any development tools locally if remote is specified.
• When remote is specified, PL/Rust should provide GUC settings to configure the remote.

Open Questions

What does that remote compilation process look like? Do we send just the user's string of Rust code, or does PL/Rust generate the entire crate and ship it off?

Could we utilize well known environments like AWS Lambda, Cloudflare workers, or Fastly's compute edge to create these artifacts?

What does this API look like?

#48 gets us to a point where we could add a state of StateRemotelyBuilding which can be reached via StateGenerated and can transition to StateBuilt.

This is no longer required.
