SaaS examples

[lukehoban]

We should build a handful of SaaS integration examples to help flesh out platform capabilities needed to support these sorts of use cases.

Some potential examples:

• [x] Salesforce polling: Poll Salesforce every 1 minute and log new items.
• [x] Send email: Send email using Mailgun/SES on user interactions.
• [ ] CSV to Salesforce data sync: Import new rows added to CSV into Salesforce every 10 minutes.
• [ ] Salesforce OAuth 2.0: Web UI endpoint with self-hosted Salesforce OAuth and Salesforce queries.
• [ ] Legacy Modernization: Put a REST API in front of a legacy system that requires files uploaded to FTP (or network file path, or similar).

We expect to add to or adjust this list.

We've built several integrations so far around Salesforce, Mailgun, SES and Twitter.

Some pieces we have not yet tackled:

• CSV to Salesforce data sync: These scenarios require connecting to Drive, Box, OneDrive, etc as a source for the CSV file, and then processing updates to the CSV. We have not yet integrated with any of these systems.
• Legacy Modernization: This scenarios tend to be about on-premises systems, we haven't yet tackled having on-premise agents. Putting a web front-end in front of SaaS systems is something we've done in many examples though.
• Salesforce OAuth 2.0: We haven't focused on 3-legged OAuth scenarios, but this scenario would flesh out the ability to build a non-trivial web application that can manage it's own OAuth flow using Lumi.

The CSV piece is likely a near term priority to flesh out as an example, the others might not be.

Great progress on this overall! I would say, let's keep chugging along on this (I'd like to spend some time here myself soon), and so I'll put this in 0.6 as a reminder to keep going.

Given the shift in focus to be broader than pure SaaS integration, we're tracking examples that fit our broader goals for the Framework at #45. Closing this one out.
