It's an interesting question if we want to do it separate like this or as part of the general ssv api?

Notes to self:

Rebased onto latest stage but eth2-key-manager and ssv-spec deps now are what we have in stage branch (meaning I need to rebase ssvlabs/ssv-spec#526 and ssvlabs/eth2-key-manager#114 and import these newer versions for code to compile correctly)

to set go.mod dependancies to the correct (latest) versions:

GOSUMDB=off GOPROXY=direct go get github.com/ssvlabs/ssv-spec@testing/preconfs-preconf-commitment-duty
GOSUMDB=off GOPROXY=direct go get github.com/ssvlabs/eth2-key-manager@testing/preconfs-preconf-commitment-duty

and also some basic TODOs left:

• fix this (concurrent calls seems to result in close of closed channel) - I need to make sure no duplicate duties can be started

close(cRunner.initialized)

• do we need to implement some kind of Auth for commit-boost API ?
  https://commit-boost.github.io/commit-boost-client/api/
• gotta document this in a comment somewhere
  Signature over preconfs domain - https://github.com/Commit-Boost/commit-boost-client/blob/c5a16eec53b7e6ce0ee5c18295565f1a0aa6e389/docs/docs/developing/commit-module.md#requesting-signatures
• check there is no inappropriate mention of slot left as the result of copy-paste

Closing this as "unplanned any time soon"
