CRD for nfd-worker config

[marquiz]

What would you like to be added:

Add a new CRD for managing the nfd-worker configuration. We could/would support the fs based configuration file as a fallback option.

Why is this needed:

Some benefits:

• Input validation, able to use e.g. openapi-spec-validation to verify configuration before accepting it
• Much faster response to config changes (no time to wait for kubelet to update the on-disk file)
• Easier to split cluster into node-groups with different configuration (just label-selector on the nfd-worker side or smth)
• Might make sense to simplify the "legacy" config file handling, dropping the dynamic update handling (fsnotify) there

Or at least properly think through if this makes sense 😅
