MarketingConnectorManager : Failed to get schema status

Zendesk Ticket Number 286122

Include detailed concise steps to reproduce the issue in a numerical format

1. Install Alloy site
2. Install Marketing package
3. Set Database Read only to true in web.config
4. Reinitialize site and get the exception in description.

Failover in DXC with this package does not work as the site does not initialize. This is something that is sold as an option.
