Support for new versions of Vault #9
Description
I'm working on integrating our internal tooling with creating vault cloudsql postgres roles. I've gotten this working locally using vault:1.8.3 but our actual dev and production environments are on vault 1.10.x. When I use vault:1.10.8 locally I get this error:
* error creating database object: invalid database version: 2 errors occurred:
* error getting plugin type: unable to get database plugin type: rpc error: code = Unavailable desc = error reading from server: EOF
* Incompatible API version with plugin. Plugin version: 5, Client versions: [4 3]
Here are the logs from the container when trying to interact and create a connection:

I'm new to using Vault and creating a plugin to interface with it but I'm happy to help contribute.
