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:
