fix/1095 - Add EventFlowMongoInitializer for MongoDB setup

[AlexGreatDev]

Introduces the EventFlowMongoInitializer class in the EventFlow.MongoDB.EventStore namespace. This class facilitates the initialization of MongoDB event persistence by utilizing an IServiceProvider to manage dependencies and service lifetimes. The Initialize method creates a scope and retrieves an instance of IMongoDbEventPersistenceInitializer to perform the necessary setup. Add your 'Program.cs' builder.Services.AddEventFlow(options => options .ConfigureMongoDb("your_connection_string", "your_db") .UseMongoDbEventStore() ); var sp = builder.Services.BuildServiceProvider(); var efInitializer = new EventFlowMongoInitializer(sp); efInitializer.Initialize(); Close #1095
