Document DVT limitations #1602
Description
We should start a limitations section in the docs.
Examples to document would be:
- Oracle LOBs are only supported via custom-query validations
- SQL Server image is unsupported due to being deprecated for 20 years and incompatible with most SQL functions
- We only support Google's own secret manager, no third party managers
- etc
I'm sure there are lots of limitations we've built in over the years that are not documented.
