## Issue Addressed #2883 ## Proposed Changes * Added `suggested-fee-recipient` & `suggested-fee-recipient-file` flags to validator client (similar to graffiti / graffiti-file implementation). * Added proposer preparation service to VC, which sends the fee-recipient of all known validators to the BN via [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api once per slot * Added [/eth/v1/validator/prepare_beacon_proposer](https://github.com/ethereum/beacon-APIs/pull/178) api endpoint and preparation data caching * Added cleanup routine to remove cached proposer preparations when not updated for 2 epochs ## Additional Info Changed the Implementation following the discussion in #2883.

//! This crate provides two major things:
|
|
//!
|
|
//! 1. The types served by the `http_api` crate.
|
|
//! 2. A wrapper around `reqwest` that forms a HTTP client, able of consuming the endpoints served
|
|
//! by the `http_api` crate.
|
|
//!
|
|
//! Eventually it would be ideal to publish this crate on crates.io, however we have some local
|
|
//! dependencies preventing this presently.
