no_std support

[dzmitry-huba]

Hello, Everyone

I was wondering if the maintainers of this project would be open to consider a no_std support for the raft-rs. I did an exercise in a fork to make changes to the codebase to make it no_std compilable (not production ready draft PR) and I would like to get feedback on the idea before preparing the official PR.

Please let me know if no_std support would be welcome. The main scenario is running Raft instance inside of the Trusted Execution Environments.

Thank you!

no_std is not a goal but nice to have. It should be OK as long as it doesn't change the std code behavior.

Thank you, I totally agree with the goal. Let me redo the PR such that no_std is an optional feature while preserving the original std behavior.
