Incorporate Monitor Ingestion Beta UX study feedback

[scottaddie]

Tracking issue to update the next Azure Monitor Ingestion release to incorporate UX study feedback.

Action items:

• README file changes:
  • Add a “Handle logs ingestion response” section that shows the response object hierarchy. See Handle logs query response for an example of this idea in the Monitor Query library’s README. Include a blurb about whether there can be more than 1 error message associated with a failed log.
  • Add guidance on factors to consider when setting the maximum concurrency level.
  • Add a “Retrieve logs” section that links to the Azure Monitor Query library’s README file.
• API changes:
  • Add new upload method overload that accepts an UploadLogsOptions type and no context parameter.
  • Update API docs for the UploadLogsResult.getErrors method to indicate whether a null or an empty list is returned when no errors are present.
• Code samples:
  • Add sample showing how to upload with the asynchronous client. The sample should include a link to Project Reactor’s docs on the Mono type.
  • Add sample showing how to replace Jackson with a different serializer via the UploadLogsOptions.getObjectSerializer method.
