Instrumentation.Http-1.8.1

OpenTelemetry.Instrumentation.Http

• Breaking Change: Fixed tracing instrumentation so that by default any
  values detected in the query string component of requests are replaced with
  the text Redacted when building the url.full tag. For example,
  ?key1=value1&key2=value2 becomes ?key1=Redacted&key2=Redacted. You can
  disable this redaction by setting the environment variable
  OTEL_DOTNET_EXPERIMENTAL_HTTPCLIENT_DISABLE_URL_QUERY_REDACTION to true.
