We add 'courserun_key' (aka "course_id" though that's technically a
misnomer) as an optional parameter to the /event endpoint url. If it
is not present, it will still be parsed out of the url, if the url is
of the right format.

Additionally, Logger.log() in js adds this parameter to its /event
call, pulling it from the $$course_id global.

This provides opportunity for MFEs to (separately) provide the key
without concern about url parsing.

add traits to segment context for enrollment activated events

- Make it easier to rotate `SECRET_KEY` by documenting this usage
  for both sensitivity and rotation process. (ARCHBOM-1676).
- Just use a hash of the secret rather than HMAC + MD5. We're not
  authenticating a message, so HMAC isn't really needed -- it just needs
  to be unique, deterministic, and irreversible. SHAKE allows generation
  of an arbitrary length hash without needing to truncate.

Also, rename tracking session ID generator for clarity -- there's no
encryption happening here.

Add additional test for existing claim of uniqueness.

Add the following monitoring custom attributes:
- segment_event_name
- segment_event_source
- segment_unexpected_context
- segment_unexpected_data

Also, this explicitly raises a validation error whenever context is a
string instead of throwing a vague TypeError.
