Rename iroha_client_cli into iroha

It makes much more sense for the end user to just call iroha when interacting with cli, wouldn't you agree?

The peer executable should be renamed too then. Maybe irohad, like some common linux daemons?

Alternatively, it might be time to consult the Japanese dictionary? We already have Torii, which is one kind of interface. The client, client CLI, and the peer CLI are interfaces too, so we could make them consistent with the rest of the Iroha lore. Might be too much though.

I wouldn't in this case. I think iroha and irohad would be more recognizable as a brand. Otherwise, it would be difficult to figure out how to use it
