Using self.fs.mon_manager in mount.py can lead to a crash since self.fs
can be None. Move is_blocklisted() to tasks.filesystem.CephCluster where
it can get access to mon_manager without depending on objects
representing Ceph FSs.

There were a couple of problems found by flake8 in the qa/
directory (most of them fixed now). Enabling flake8 during the usual
check runs hopefully avoids adding new issues in the future.
