PR body:
"""
# Enable literal-comparison linter again

The literal comparison linter checks for "value is 0" or "value is
''".

# Fix wrong use of identity operation

Strings should not be compared with the identity operation 'is' or 'is
not'.

# Add new env vars to pylint plugin

The vars api.env.host_princ and smb_princ where introduced a while ago.
Sometimes parallel linting complain about the attributes. Add both to
the list of known members in pylint_plugins.py.
