Update bandit usage

This patch replaces explicit list of bandit tests to run
with a list of bandit tests to skip (only 3 are skipped).

It also replaces legacy-formatted bandit.yaml with what current
bandit version expects,
and improves the 'bandit' tox target somewhat.

# One of the blacklisted imports is the subprocess module. Keystone
# has to import the subprocess module in a single module for
# eventlet support so in most cases bandit won't be able to detect
# that subprocess is even being imported. Also, Bandit's
# recommendation is just to check that the use is safe without any
# documentation on what safe or unsafe usage is. So this test is
