Tool View schema definition

Related to #120

I went to generate a Tool View manifest and noticed the new attributes were not included in the sheet.

@aditigopalan mentioned that the dependsOn field had not been updated to reflect the updated Tool View model, but there are a couple additional things to address before the model is integrated:

• new attributes must be added to the dependsOn column of the Tool View attribute row
• Valid values CSVs must be created for any new attributes with valid values
• mapping.yml must be updated to ensure update_valid_values.py maps the valid values CSV to the Valid Values column of new attributes
