Done using isort[1], with the following command:
```
isort -rc ./app ./tests
```
Adds linting to the `run_tests.sh` script to stop badly-sorted imports
getting re-introduced.
Chosen style is ‘Vertical Hanging Indent’ with trailing commas, because
I think it gives the cleanest diffs, eg:
```
from third_party import (
lib1,
lib2,
lib3,
lib4,
)
```

Use the new version of the notifications-python-client. This version no longer adds the req and pay to the claims of the jwt.
The change is backward compatible so an older client that sends a JWT with the extra claims will pass authentication.
Once all the clients have been updated to not include the extra claims some updates to exclude them from the method signatures will happen as well.
The documentation has been updated to reflect this change.
