NOTE: in addition to the orginal backport, this patch adds the following
changes. The changes has to be combined into a single patch in order to
avoid circular dependencies.

1. fixed bandit complains in keystoneclient/common/cms.py. The literal 'sha256'
is the default hash algorithm, not a sensitive password. Marking it as false
positive so bandit can stop chirping.

2. combined with cherry pick from commit
f2d3fec9b254f9c47e97ddf48e3c5f7614b87f1b to avoid circular dependency. Without
combining them, neither backport will pass all the gates since pep8 has
switched over to use python3 now.

3. combined with cherry pick from commit
b29f478f28c4989156cfe87392cbd308e3f55c1e to avoid circular dependency. Without
combining them, neither backport will pass all the gates since bandit will
have a false positive on the hash algorithm.
