Proposed Commit Message

pylint: silence errors on compat code for old jsonschema

Let's silence the errors which are emitted by pylint on
a code path that exists only for backwards compatibility
with older versions of jsonschema. Pylint can't be aware
of the library version check we're doing.

Additional Context

Spotted by Jenkins:

************* Module cloudinit.config.schema
cloudinit/config/schema.py:121: [E1101(no-member), get_jsonschema_validator] Class 'Validator' has no 'DEFAULT_TYPES' member
cloudinit/config/schema.py:126: [E1123(unexpected-keyword-arg), get_jsonschema_validator] Unexpected keyword argument 'default_types' in function call

Test Steps

Run tox -e pylint on a >= Focal system and verify that pylint emits no errors.

I rebased by branch and force-pushed, let's see what Travis does.
