Michael Sproul e961ff60b4 Implement standard keystore API (#2736) ... ## Issue Addressed Implements the standard key manager API from https://ethereum.github.io/keymanager-APIs/, formerly https://github.com/ethereum/beacon-APIs/pull/151 Related to https://github.com/sigp/lighthouse/issues/2557 ## Proposed Changes - [x] Add all of the new endpoints from the standard API: GET, POST and DELETE. - [x] Add a `validators.enabled` column to the slashing protection database to support atomic disable + export. - [x] Add tests for all the common sequential accesses of the API - [x] Add tests for interactions with remote signer validators - [x] Add end-to-end tests for migration of validators from one VC to another - [x] Implement the authentication scheme from the standard (token bearer auth) ## Additional Info The `enabled` column in the validators SQL database is necessary to prevent a race condition when exporting slashing protection data. Without the slashing protection database having a way of knowing that a key has been disabled, a concurrent request to sign a message could insert a new record into the database. The `delete_concurrent_with_signing` test exercises this code path, and was indeed failing before the `enabled` column was added. The validator client authentication has been modified from basic auth to bearer auth, with basic auth preserved for backwards compatibility.		2022-01-30 23:22:04 +00:00
