1246639 - Auto generate PayloadSchema() methods in engines base on buildtime discovery of engines

Status: RESOLVED FIXED

(Taskcluster :: Workers, defect)

Description

[Pete Moore [:pmoore][:pete]]

We will have json schemas checked into the source tree, and we can use these to generate the PayloadSchema() methods for all of the engines at build time.

We are essentially doing this now. Rather than generating the PayloadSchema methods, we are generating a `payloadSchema` unexported package variable, which the PayloadSchema methods can simply return.

See e.g. https://github.com/taskcluster/taskcluster-worker/blob/21110becb3f9f65f45c17fded3b550f87951a5ac/engines/mock/mockengine.go#L40 which returns the value in the generated code from https://github.com/taskcluster/taskcluster-worker/blob/21110becb3f9f65f45c17fded3b550f87951a5ac/engines/mock/generated_payloadschema.go#L27.
