Auto-detection of Schema

[joepavitt]

We've proposed (in #3445) the idea of offering a Schema Builder, but as pointed out by customers we've discussed this with, this would be a significant undertaking to flesh out and define for full scale factory ecosystems, etc.

Alternatively, we could provide an "auto-detection" option, whereby, based on values we're seeing come into different topics, we could try to offer proposals for schemas, e.g. payloads that are email, number, string, array`, or whichever definitions we decide upon.
