[DotNetCore] Refactor Serilog ApplicationInsights and AzureAnalytics to extensions

[kdcllc]

At the moment there is no way to use Serilog with IHost for

1. Serilog.Sinks.ApplicationInsights
2. Serilog.Sinks.AzureAnalytics

Refactor func to Bet.Extensions.Logging

Add this package to support the functionality

<PackageReference Include="Serilog.Extensions.Hosting" Version="3.0.0" />

Final result should be

            return Host.CreateDefaultBuilder(args)
                .UseSerilog((hostingContext, loggerBuilder) =>
                {
                    var applicationName = $"Worker-{hostingContext.HostingEnvironment.EnvironmentName}";
                    loggerBuilder
                            .ReadFrom.Configuration(hostingContext.Configuration)
                            .Enrich.FromLogContext()
                            .WriteTo.Console()
                            .AddApplicationInsights(hostingContext.Configuration)
                            .AddAzureLogAnalytics(hostingContext.Configuration, applicationName: applicationName);
                });
