[NR-266264] Connect agent to live harvest v5 response

[cthomas-newrelic]

NR-266264 Implement v5/connect request map headers

Moves to /mobile/v5/connect endpoint. Integrates new request_map_headers property on connect response.

NR-251338 Add log/supportability metrics to count AEI

Logs count of visited or skipped AEI records. Adds:

• Supportability/AgentHealth/ApplicationExitInfo/visited
  • sample new AEI records recorded.
• Supportability/AgentHealth/ApplicationExitInfo/skipped
  • sample count of AEI records already recorded

NR-266264 Update v5/connect response fields

The v5 spec adds/removes fields from the expected HarvestConfiguration class. Most changes are benign and fall back to default values, others like application ID was used in agent code.

Refactors harvest components to add a HarvestConfugurable interface, to normalize the exchange of config data. Fixes misnamed config elements. Removes unused properties form SavedState.
