Add columns to VBN metadata tables

[danielsf]

Corbett is working to update the spreadsheet linked to in ecephys_etl_pipelines issue 38 with the "abnormalities" columns they want added to the metadata tables. Since we are not going to be modifying the schema of the LIMS database tables, we need to modify the input.json schema for the metadata_writer to accept that data and write it to the appropriate table.

Also note that some new sessions and probes have been deemed unfit for release, notably probes A, B, and C for session 1109680280 and all of session 1098350754.

These should be added/subtracted from whatever input.jsons are used to produce the final data and metadata sets.
