Event-based Post-deployment follow-ups

[ylembachar]

Further tests

• Limit the number of allowed API calls following the Chiado stress tests
• Investivate why the stress tests with 100 registrations at a time sometimes fail
• Roll-out the event smoke tests on Mainnet and some stress tests

Improvements:

• See closed EPIC here for further improvements: EPIC: Improvements needed on the event-based features #84

• keys on Mainnet

• demos? / deprioritize for now until business opp.

Anything else: TBD
