Remove data sub dictionary and move everything to top level

[FragmentedPacket]

Fixes #58

• Remove custom NautobotAnsibleModule that was being used for custom validation due to having nested data
• Accept within NatubotModule argument for which keys to remove for payload
• Create _build_payload to remove unnecessary keys to send to Nautobot
• Fix documentation string
• Fix arg spec for change in data

TODO:

• Unit test for _build_payload
• True up unit test data for passing in new module args
• True up all other modules (should be pretty easy lift and shift)
• Integration tests (separate PR due to size and integration tests not existing at the moment)

One small change requested for semantic versioning since this will be a breaking change.
