Field name standardization

[tsellers-r7]

Description

This PR adds field names (os.vendor, service.product, etc) to bin/recog_standarize. This should help us identify field name typos as well as be a bit more intentional when we introduce a new field.

How Has This Been Tested?

ruby bin/recog_standardize xml/*.xml, rspec, etc.

Types of changes

• New feature (non-breaking change which adds functionality)

Checklist:

• [ ] I have updated the documentation accordingly (or changes are not required).
• [ ] I have added tests to cover my changes (or new tests are not required).
• [ ] All new and existing tests passed.

@hdm - in light of the ow.device typo you caught earlier I figured it'd be time to implement this to help catch such things.
