Integrate with opentelemetry-android

[surbhiia]

This PR covers the following:

• Setup for installing opentelemetry-android instrumentations
• Integrated HttpURLConnection auto-instrumentation
• Upgrades to necessary libraries as needed for the integration:
  • Desugar lib
  • Bytebuddy version
  • oTel semantic conventions
• Forcing earlier versions of remaining to maintain compatibility with our SDK
  • kotlin-stdlib (1.8.0 - our SDK requirement)
  • androidx.core:core (last most used stable version 1.31.1)
  • androidx.core:core-ktx (last most used stable version 1.31.1)
• Updates needed in plugin code and exsuring it’s usage in sample app and testing telemetry generation
• Upgrades to certain API names to tell them apart from similar APIs coming from upstream like:
  • OpenTelemtry -> SplunkRumOpenTelemtrySdk
  • SessionManager -> SplunkSessionManager (this will be replaced later anyway when upstream SessionManager is used instead)

Upcoming in future PRs:

• Based on one/two plugin approach we decide - integrate okHttp3 auto-instrumentation along with the changes needed for that.
• Add additional attributes once atrribute extractors PR upstream is merged.
• Validate all attributes for Network Request spans once we have all of the SDK setup for attributes in place.
