Description

This PR exploded in size and contains quite a bit of changes (Some of the changes were too related). Here's what's been changed:

• Refactored the CommandMetricsMeterProviderBuilderExtensions into a generic class for OpenTelemetry extension methods. It includes a new extension method for adding the core MuzakBot sources to the trace provider.
• Added classes to use for iTunes API activity traces.
• Added classes to use for MusicBrainz API activity traces.
• Created classes to handle creating activities for OdesliService, ItunesApiService, MusicBrainzService, and ShareMusicCommandModule respectively.
  • They contain extension methods for creating Activity objects from ActivitySource objects.
• Implemented activity traces into OdesliService, ItunesApiService, and MusicBrainzService.
• Optimized the handling of HttpClient usage in OdesliService, ItunesApiService, and MusicBrainzService.
  • Primarily adding a using statement when the HttpClient is initialized so it's properly disposed of at the end of execution.
• Added code docs for many new and existing classes.
• Implemented passing the ID of the Activity object to dependent services/methods used in ShareMusicCommandModule.
  • This is to ensure those methods are correlated to the executed commands in the telemetry.
