Initial simple separation to get the process of extracting dvc-objects
and dvc-data packages out of dvc.
dvc-objects is for:
* defining base Object (aka HashFile) and ObjectDB
* providing tools to work with those objects (check/transfer/etc)
* etc
dvc-data is for:
* defining higher level objects (e.g. Tree)
* bulding objects from the workspace (aka staging)
* projecting objects back into the workspace (aka checkout)
* comparing Tree objects (aka diff)
* defining misc object databases (e.g LocalObjectDB)
* higher-level transfer (e.g. with Tree indexes)
* etc
For example, the objects we use in run-cache are based on dvc-objects
and not on dvc-data, as they have absolutely nothing to do with data
management.
There are still some mixups in the code that will be addressed in the
followups.
Intermediate PR in removing path_info from our code base.
It is completely removed from the main codebase and is still
being used in tests, which will be migrated in the followups.
For fs-specific simple path manipulation, we've introduced
`fs.path` helper (similar to `os.path`).
Fixes#6774
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.
* dvc: get rid of DirInfo
DirInfo was created before we had proper objects, as a way to have a
structure that represents a staged directory. Right now we have a
dedicated Tree object that is specifically meant for that.
As a result, HashInfo no longer needs to have dir_info and we no longer
need `get_hash/get_dir_hash` helpers.
* objects: move Tree into tree.py
Currently we are converting dir_info to/from lists all the time.
The reason is that dir_info is stored as list of dicts in *.dir files,
but that makes it hard to work with. In addition to that, we will likely
be changing .dir file format in the near future #829, so we need to
abstract away dir_info into something that we won't care how it will be
stored on disk.

Outputs and dependencies don't really care about the remotes, as they
don't do any pushing or pulling. What they really need are the trees,
so let's use them directly.
Part of #4050
* remote: move get_file_checksum() into tree
* makes RemoteTree and RepoTree consistent with regard to checksum
calculation
* remote: save() now takes explicit tree parameter
* when tree is remote.tree, save will be a move + link operation
(same as default existing behavior)
* when saving path from a different tree, save will be a copy operation
* tests: update for moved remote/tree functions
* remote: move get_checksum into tree
* remote: separate cloud remote and cache classes
* tests: update unit tests for remote/cache separation
* remote: cloud cache should extend cloud remote
* remote: move LocalRemote.get
* tests: update func tests
* dependency: update for moved get_checksum
* remote: fix state lookup bug
* BaseRemote: start moving tree functions into BaseRemoteTree
* remote: add LocalRemoteTree
* remote: add cloud remote trees
* remote: move remove(), makedirs() into tree
* remote: move move(), copy(), symlink(), hardlink(), reflink() into tree
* fix attributes for moved remote methods
* tests: update unit tests for moved remote tree methods
* tests: mv unit/remote/test_remote_dir.py unit/remote/test_remote_tree.py
* fix attributes for moved remote tree functions
* tests: update func tests for moved remote tree methods
* test fixes
* fix DS warnings
* add: auto convert absolute_path => relative
- fixes#2955
* use path_isin
* catch-all absolute paths in repo
* unneeded leftover
* revert realtive imports for later
* output: move abs2relpath from Base to Local
* output:local:fix parse_path
* remove path_info
* test:local versus base abs2relpath
* test:fix remaining abs2relpath test
* output: local path relative to wdir
* output: local: modify path before inheritance
* output: local: minor inheritance fix
* test: local: split output test
* test: local: positively explicit
