feat: Adapt telemetry to cater for logged out cases

[justinvdm]

Determining distinct id (to identify distinct users)

• If user logged in, use the user id as the distinct id

• Otherwise if not CI, get/create anonymous id + use this as the distinct id

• Otherwise if in CI and project id exists, use <projectId>:ci as the distinct id

• Otherwise do not send metrics (e.g. if logged out CI user)

  Aliasing:

• When logged in, if previous distinct id was anonymous id, alias anonymous id to userId
