* Fix error messages (they must be in the form "doing something")
* Improve/reword some error messages
* Document the identity.json existance in the cli docs
* Fix a bunch of typos
* Fix missing folder path in the --help
* Fix cluster not locking when configuration is not there but folder is
* Fix force flag not overriding the config overwrite prompt
* Fix deletion of Raft state on re-init (not necessary if identity persists)
* Fix overwriting on identity (should not be overwritten if already exists)
Much of this paves the way to be able to run without service.json:
* Either taking default values (and using env vars) - maybe someday
* Either by getting a configuration template it from somewhere (ipfs, http)
at runtime - sooner.
