Allow custom logger providers

[bobted]

Since both properties of BaseBuilder are protected internal, it is difficult to add custom ILoggerProvider instances to the default LoggerFactory in the connection.

I understand there is an extension method to provide a new instance of LoggerFactory, but in my case, I'd rather keep the LoggerFactory that the connection is using separate from the LoggerFactory that the rest of the app is using. However, I'd like to inject a LoggerProvider (i.e. Serilog) so the behavior of the logging can be managed via configuration.

I think the easiest solution would be an additional extension method in Xeeny.Extensions.Loggers.BaseBuilderExtenions.

        public static TBuilder WithCustomLoggerProvider<TBuilder>(this TBuilder builder, ILoggerProvider provider)
            where TBuilder : BaseBuilder
        {
            builder.LoggerFactory.AddProvider(provider);
            return builder;
        }
