When the test suite is running, we don't want to be triggering the startup of daemons for the secondary drivers. Thus we must provide a way to set a custom connection for the secondary drivers, to override the default logic which opens a new connection. This will also be useful for code where we have a whole set of separate functions calls all needing the secret driver. Currently the connection to the secret driver is opened & closed many times in quick succession. This will allow us to pre-open a connection temporarily, improving the performance of startup.
