Updates base and Python dependencies

[hardbyte]

Kept pulling on a bit of string here... would be a lot easier to just move off alpine.

I've updated all the pinned dependencies in the base dockerfile, including adding the rust compiler so we can build the cryptography package.

Then it looks like the current data61 libraries are incompatible with each other:

Collecting blocklib>=0.1.4
  Downloading blocklib-0.1.7-py3-none-any.whl (22 kB)
INFO: pip is looking at multiple versions of anonlink to determine which version is compatible with other requirements. This could take a while.
ERROR: Cannot install -r requirements.txt (line 2) and minio==5.0.10 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested minio==5.0.10
    anonlink-client 0.1.4 depends on minio>=6.0.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/user_guide/#fixing-conflicting-dependencies

So I've updated all the Python dependencies (dependabot is going to be stoked) and told the ResolutionImpossible where to go.

Then anonlink wouldn't build on alpine...

So I updated anonlink to fix this

  ERROR: Failed building wheel for anonlink

Until there is a new release of anonlink I've just pinned the commit hash that fixes the compilation error in the base/requirement.txt file.

I couldn't help myself, I had to update from minio v5 to v7 too... which obviously involved a bugfix in minio-py

@wilko77 I ran out of steam when I hit pickled bitarray objects used in test data, I've rolled back the bitarray dependency. Everything I've updated seems to be working.

The current CI failure appears to be entirely unrelated, while cleaning up after testing kubectl/helm is trying to delete a resource that is already gone:

Error from server (NotFound): error when deleting "/home/vsts/work/_temp/baked-template-20313a84-527c-46ec-b3fb-c14a34c8715c.yaml": pods "azk45569a2-memstore-configmap-test" not found

Without this line the cryptography package is built instead of installed as a wheel!

Wow. "Just" some dependency updates.
It is a bit worrying that we rely on such an unstable API in minio...
Maybe wait for the new anonlink release and reference that instead.
