Ruslan Kuprieiev 612f3039e0 repo: move state/index/data_index to site_cache_dir
We use all of these for optimization and should not depend on a potentially slow or broken
filesystem on which repository resides (could be HDD or CIFS/NFS/overlayfs/etc).

This PR means a few things:
    * all odd filesystems that dvc repo might be on will work quickly out of the box
    * when we start caching cloned repositories for `dvc get/import`, we will be
      able to cache indexes for them as well (note that bare clones don't have a
      worktree so there is no place for .dvc/tmp with the old approach).
    * `index.dir` and `state.dir` are now obsolete.
    * `dvc init` will cleanup site_cache_dir.
