azure storage driver to use the new SDK. Add support for client
secret and MSI authentication schemes in addition to shared key
authentication.
Implement rootDirectory support for the azure storage driver to mirror
the S3 driver.

Go 1.16 reached end of life, so update to the current version of Go, but also
run CI on the previous version (which is still supported).
We should probably also decide wether or not we want the Dockerfiles to pin to
a specific minor version; this makes the releases more deterministic.
