## Issue Addressed This PR is a subset of the changes in #3134. Unstable will still not function correctly with the new builder spec once this is merged, #3134 should be used on testnets ## Proposed Changes - Removes redundancy in "builders" (servers implementing the builder spec) - Renames `payload-builder` flag to `builder` - Moves from old builder RPC API to new HTTP API, but does not implement the validator registration API (implemented in https://github.com/sigp/lighthouse/pull/3194) Co-authored-by: sean <seananderson33@gmail.com> Co-authored-by: realbigsean <sean@sigmaprime.io>
