We used to have it named `cache` before, but these days it is clear that
you can have three odbs: just odb (e.g. in-memory), cache (typically local)
or remote (typically cloud). Fixing naming here before proceeding with
introducing `out.odb` and `out.cache`.
In preparation for migration to https://github.com/iterative/dvc-data/pull/304
By splitting dvc.cli into a module, we'll be able to share cli-related
utilities, split parser-related stuffs into smaller parts, improve
reusability and improve API for command extensions in the future.
Windows (or rather NTFS) doesn't allow deleting read-only files, which made us
try to chmod +w first. But that is not necessery on Linux and Mac, and
has led to unnecessary cache file mode changes, which was causing issues
in shared cache scenario when a user that doesn't own a file was trying
to automatically protect it.
