OpenTelemetry

• Added Sdk.CreateLoggerProviderBuilder method and support for dependency
  injection scenarios when configuring OpenTelemetryLoggerProvider
  (#3504)

OpenTelemetry.Api

• Updated to System.Diagnostics.DiagnosticSource preview version 7.0.0.

  With this update, applications targeting .NET 5 and lower will receive a
  warning at build time as described here
  (note: building using older versions of the .NET SDK produces an error at
  build time). This is because .NET 5 reached EOL in May 2022 and .NET
  Core 3.1 reaches EOL in December 2022.

  There is no guarantee that System.Diagnostics.DiagnosticSource will continue
  to work on older versions of .NET. However, the build warning can be
  suppressed by setting the SuppressTfmSupportBuildWarnings MSBuild property.

  This does not affect applications targeting .NET Framework.

OpenTelemetry.Exporter.Console

• Improve the conversion and formatting of attribute values.
  The list of data types that must be supported per the
  OpenTelemetry specification

  built-in value types
  are supported by converting to a long or double as appropriate except for
  numeric types that could cause overflow (ulong) or rounding (decimal)
  which are converted to strings. Non-numeric built-in types - string,
  char, bool are supported. All other types are converted to a string.
  Array values are also supported.
