tests: Configure logging for all test files

all test_*.py files now accept zero or more '-v' to increase tuf
logging level. The default is now ERROR.

default: ERROR
"-v":    ERROR, but unittest prints test names
"-vv":   WARNING
"-vvv":  INFO
"-vvvv": DEBUG

Example to run a single test with DEBUG level:
  python3 test_updater.py -vvvv TestUpdater.test_4_refresh

Also make test_log.py restore the log level it modifies during test.

Fixes #1093
