Not all commands respect --api

Description:

When using a remote node through the command line (ex: ipfs --api="/dns4/ipfs.io/tcp/5001" id) I found out that not all commands respect the --api. As an example, version entirely ignore the flag and return the version of the command line binary instead of the remote version.

My understanding is that it's because some commands are marked a doesNotUseRepo in https://github.com/ipfs/go-ipfs/blob/master/cmd/ipfs/ipfs.go#L86.

The problem is, not using the repo and not making API call are two different concepts.

While it make sense to not use the repo for cid or commands because the command line binary is capable of dealing with the input on its own, commands like version or even init and config/edit should still honor the --api flag, version especially.

So, init can't use the API because it has to be run before the daemon starts. However, I agree version should fetch the remote version.
