Pre-requisite for removing fs.path_info and switching to regular strings
as paths in filesystems.
With new filesystems we no longer need the zoo of different dependency
and output types, as most of them are now just handled by the underlying
filesystem. Though deps/outs are still due for a refactor in other
aspects.
Checkout is an operation that builds object from cache(aka object
database) in a particular tree(aka filesystem). Thus it shouldn't be
part of the object database itself nor of the filesystem.
Pre-requisite for #5337
* state: add simple reentrance
* state: pass Repo instead of LocalCache
* state: use granularly
Users could still load state preemptively if they want to bulk up
the operations, but other than that tree/cache will just load it
when they need it.
* repro: support --pull
This option allows run-cache to pull the cache for the outputs
when restoring a stage instead of pulling everything at once during
`dvc pull --run-cache`.
Fixes#4223
* repro: adjust --pull help
By itself `self.info` is quite confusing, as it is not clear what it is
about. Using `hash_info` makes much more sense and is required to
support alternative hash types.
