test: improve modularization

Browse Source 
This improves debugging and experimenting by making it easy to compose fine-grained
scenarios that have specific tests and features enabled.

The VM test output now includes the subtest name and duration.

Remove the 'raise Exception()' hack for interactive mode.

Run 'banlist-and-restart' test before 'backups'. This speeds up the test
by avoiding an extra shutdown of all bitcoin-related services.
