Add extra analytics for notification performance

[jmartinesp]

Content

Add technical spans to track how long a notification fetching work request takes to run, then how long it takes to actually fetch the events for the notifications.

An example of one of this transactions is here.

Motivation and context

Try to understand what can make notification fetching slow.

Tests

Not much to test, other than running the branch with analytics enabled and looking at Sentry after a while.
