* [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
