Allow registered dependencies to be used when configuring endpoints with UseNServiceBus

Describe the suggested improvement

Is your improvement related to a problem? Please describe.

It doesn't seem possible to resolve a dependency from the ServiceProvider for use when calling UseNServiceBus.

The specific instance where this could be helpful is when using SqlPersistance with MutlipleTenants.

Example:

  Host.CreateDefaultBuilder(args)
    .ConfigureServices(services =>
    {
        services.AddSingleton<ConnectionStringBuilder>();
    })
    .UseNServiceBus(c =>
    {
      var endpointConfiguration = new EndpointConfiguration(endpointName);
    
      var persistence = endpointConfiguration.UsePersistence<SqlPersistence>();
        persistence.SqlDialect<SqlDialect.MsSqlServer>();
    
      persistence.MultiTenantConnectionBuilder(tenantIdHeaderName: "TenantId",
            buildConnectionFromTenantData:
            tenantId =>
            {            
                return new //Can't figure out how to resolve ConnectionStringBuilder 
                   SqlConnection(ConnectionStringBuilder.GetConnectionStringForTenant(tenantId)); 
            });
     }

Describe the suggested solution

Provide some way to resolve the dependencies inside UseNServiceBus

Describe alternatives you've considered

A static method is being used to provide the functionality to get the tenant-specific connection string.
