feat(tracing): Submit initial version of tracing analysis scripts

[tayfunelmas]

The analysis happens in three stages:

1. We fetch the telemetry traces from the raw_trace service and convert it to the corresponding Python objects representing the spans and events in raw form.
2. We generate the block and shard histories as the intermediate form, collecting the selected spans and events only.
3. We convert the block and shard histories in the intermediate form to the Firefox profiler input format.

There will likely be more changes to polish the format and add more event/span types, but wanted to submit this version as the beginning to track the history of changes later.

We also add update some span/event logs to collect the relevant fields.

Example output json file for Firefox profiler is attached.
