BEFFE wont run in Production without SQLServerStore nor AzureServiceBusStore injected to runtime

[jezzsantos]

WebsiteHost Host is loading both SqlServerStore and AzureServiceBusStore at runtime, into the DI container, in production builds!

We do not expect this host (and some others like AzureFunctions/AWS Lambdas) to require either of these services! (WE DONT THINK)

Either we need to not inject them for BEFFE's hosts or we have to inject them and they require the necessary configuration in appsettings.json.

The adverse side-effect is potentially, extra consumed memory, and increased cold/warm start-times, particularly acute in server-less environments.

[jezzsantos]

Perhaps we use the HostOptions and a property like UsesPersistence and UsesMessaging to make this distinction.
And then we can sidestep their registration in the container (and remove the settings from the appsettings.json for those hosts)

[jezzsantos]

Including all persistent stores in the BEFFE and/or other host types (such as AzureFunctions/Lambdas) can lead to performance bottlenecks in unexpected ways.

For example libraries like Marten IEventStore when instantiated performs very expensive (in time and memory) code generation. This increases cold/warm starts. In an AWS server-less environment this is critical to avoid.
