This PR introduces tracking of remote names and local names of files in snapshots to disambiguate between files which might have the same remote name and handle clean deleting of files whose remote name changes due (eg. python notebook getting converted to a python notebook)
This PR does multiple things, which are:
1. Creates .databricks dir according to outcomes concluded in "bricks
configuration principles"
2. Puts the sync snapshots into a file whose names is tagged with
md5(concat(host, remote-path))
3. Saves both host and username in the bricks snapshot for debuggability
Tested manually:
