Move bitops defaults out of the core and into the schema

**Is your feature request related to a problem? Please describe.**
Currently the default values for BitOps are defined in in the settings.py file. The defaults need to be moved out of the `settings.py` file and into the `bitops.schema.yaml` file.

Read settings.py to locate the current BitOps default values, then inspect bitops.schema.yaml to understand where schema defaults belong. Move the BitOps defaults so they are defined in bitops.schema.yaml rather than settings.py, and verify that settings.py no longer owns them.
