refactor(types)!: move worker type to server and nest API object

[ecrupper]

Proposal ref: go-vela/community#639

@jbrockopp saw this refactor as a good opportunity to migrate off of the go-vela/types repo a while back.

Starting with worker since it is a very low user-requested resource but is still leveraged often enough by the Vela application that we would know if something wasn't quite right very early.

I was also itching to start with worker, as the admin page would benefit greatly from clickable build links sourced from the ListWorkers API response.

As a visual:

looks good overall. it seems like the we would have to mark this as breaking with the field name change here https://github.com/go-vela/server/pull/997/files#diff-a0e7f3f0dda9cc1df4b6b67ce3b81bdf66406453632b6777ad555838eaea080aR22 (see https://github.com/go-vela/types/blob/bab8877f46068f83fc2775f6148303be018ae248/library/worker.go#L20 for reference). in local testing, "running_builds" never showed up in the response. i believe we need accompanying changes in sdk-go and worker.
