Expected client behavior after CLIENT REPLY OFF

[Yury-Fridlyand]

After sending CLIENT REPLY OFF or CLIENT REPLY SKIP server stops replying, but keeps receiving and processing commands. Currently, all clients don't work properly, because all promices/futures get timed out. If we leave them unawaited we aren't guaranteed that they ever executed (and it also causes code validation issues). If we await for them, but ignore errors - client gets locked on every command until timeout; the code becomes ugly as well.

Things to consider:

1. reply-less mode of communication
2. how to resolve/complete futures/promises?
3. how to avoid type casting errors for these futures?
4. how to handle a transaction (be aware of [BUG] CLIENT REPLY OFF in transaction handled incorrectly valkey#1268)?
5. GLIDE should also handle restoring replies with CLIENT REPLY ON
6. GLIDE shoudl skip response conversion in reply-less mode
