Airtable API Proxy

[whoisgina]

Replace direct Airtable API communication with a proxied approach using serverless functions

• Remove references to secrets from client-side code
• Add netlify-lambda for interfacing with Netlify Functions and enabling local development
• Add lambda functions to handle GET and PATCH requests to the Airtable API using secrets isolated from the client

It would be useful to stub out the methods such a plugin would need to implement. Depending on how you are using Airtable in the app, it may be useful to define methods that:

• List all the available sheets in a table
• Lists all records in a given sheet
• Lists all the "attributes" (columns) used by records in a given table
• Find the first/last/other specific-criteria-matching record in a given table
• Update a given record by providing some kind of attributes object as a payload

Also, we're going to want to think about how to handle success and failure whenever communication is taking place with a remote service like Airtable. I assume some of the above behavior may be useful and some may not, right now.

We have replaced the custom Airtable Vue plugin with serverless functions that proxy API requests in order to keep secrets safely isolated from the client.
