Update Custom Fields Initializer for Netbox 2.7 ...

follows:

  - the `selection` type was changed to `select`
- the filter_logic must be lower case

This is to achieve compatibility with the naming schema that
Netbox uses internally. It allows us to become forward compatible
in case Netbox ever introduces a new type for custom fields.
