* [JaegerExporter] Periodically flush undelivered Spans
A Span will never be delivered if the maximum batch size isn't hit or the
component is not torn down. We need to flush these undelivered Spans.
The timer is enabled if a Span is batched up and not sent and then disabled
the next time the batch is flushed.
* Forgot to Dispose the timer
* Switching to SemaphoreSlim for the async aware lock
* add extension methods to register prometheus exporter
- IApplicationBuilder
- WebHostBuilder
* update http and hosting abstractions packages to 2.2.0
* fix web host extensions
* extract metricHttpServer from PrometheusExporter
* remove moq dependency in promethus tests
* remove IApplicationBuilder and IWebHostBuilder prometheus extensions
* revert changes to prometheus csproj
* rename MetricsHttpServer to PrometheusExporterMetricsHttpServer
* add IDisposeable to PrometheusExporterMetricsHttpServer
* refactor PrometheusExporterMetricsHttpServer to not require PromethusOptions as param
* move CancellationToken from constructor to Start method
* check http servere is both not null and listening before calling stop

The TraceId translation to High/Low longs handles endianess but the SpanId did not.
I also took the opportunity to switch to Span<byte> and reinterpret cast to eliminate byte array allocations.
Verified speed + 0 allocations using Benchmark

* add generic logger exporter
* remove string builder entry in ExportAsync
* use logger spans
* add null checking for attriute and events
* rename LoggingExporter to LoggerExporter
* refactor LoggerExporter into ConsoleExporter
reduces potential risk of depending on ILogger and having to maintain / use incorrectly. This exporter is designed during learning / debug scenarios.
* add experimental to package tags
* rename LoggingOptions to ConsoleOptions
* refactor ConsoleExporter to use System.Text.JsonSerializer
- increases minimum framework version to `net461`
* add readme to ConsoleExporter
* update tracer name to be console-test
* write each span JSOM directly to Console instad of using StringBuilder
* update ConsoleExporter to use SpanData
