Add telemetry upload functionality

[weikanglim]

Add uploader that reads the telemetry storage queue and uploads telemetry. Also includes some surrounding functionality so that we can test the full telemetry pipeline. Fixes #458

The telemetry pipeline looks like:

1. Telemetry is emitted using an OTel tracer. The tracer is configured to use our storage exporter. (telemetry.go)
2. Traces are exported by our storage exporter. Traces are serialized in AppInsights format, then stored on disk. (storage_exporter.go)
3. In a separate background process, we run the background upload process via RunBackgroundUpload (telemetry.go). Our Uploader is invoked to upload items in the queue. (uploader.go)

The full telemetry pipeline (with telemetry queue mocked out as an in-memory queue) is tested in uploader_test.go.
