MongoDbHealthCheckBuilderExtensions add factory delegate with service provider input [Enhancement Request]

[georgy93]

Hello!

Is it possible to provide an option for MongoDB Healthcheck to use a factory delegate for creating the connection string.

My use case is that I have template connection string in my appsettings and then, at aplication startup, I make a call to Vault to receive credentials and update the connection string template with them.
However, I cannot currently pass the updated connection string to the HealthCheck.

Adding IHealthChecksBuilder overload with Func<IServiceProvider, string> mongodbConnectionStringFactory will solve my problem, because it will always read an up-to-date connection string.

This is already implemented for HealthChecks.SqlServer
