## Changes
- added saving profile to `~/.databrickscfg` whenever we do `databricks
auth login`.
- we either match profile by account id / canonical host or introduce
the new one from deployment name.
- fail on multiple profiles with matching accounts or workspace hosts.
- overriding `~/.databrickscfg` keeps the (valid) comments, but
reformats the file.
