Unit tests are now run in all three big OS.
Some of the changes are to make the tests green for windows while we are
skipping some of the other tests on windows/macOS to make the tests
pass. This is a temporary measure and we will incrementally migrate
these tests over so there is parity in unit testing along all three
environments!
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:

By:
* Add .gitkeep to retain test fixture directories under
./python/testdata
* Move GitHub related functionality to ./experimental (it is not in use)
* Comment out test in ./cmd/sync
* Fix test in ./git
Functionality from `io/ioutil` has moved to the `io` and `os` packages
in go1.16 ([reference](https://pkg.go.dev/io/ioutil)).
Confirmed that staticcheck passes when run with:
```
staticcheck -checks SA1019 ./...
```
