feat: Add provisionerd protobuf definitions (coder#83)

* feat: Add parameter and jobs database schema

This modifies a prior migration which is typically forbidden,
but because we're pre-production deployment I felt grouping
would be helpful to future contributors.

This adds database functions that are required for the provisioner
daemon and job queue logic.

* feat: Compute project build parameters

Adds a projectparameter package to compute build-time project
values for a provided scope.

This package will be used to return which variables are being
used for a build, and can visually indicate the hierarchy to
a user.

* Fix terraform provisioner

* feat: Add provisionerd protobuf definitions

Provisionerd communicates with coderd over a multiplexed
WebSocket serving dRPC. This adds a roughly accurate protocol
definition.

It shares definitions with "provisioner.proto" for simple
interop with provisioners!
