Actual E2E tests for Live Frontend Flow

[fhnaumann]

Create actual e2e tests that mimic how the user would interact with the system.

Integration Test: Plugin -> AWS

• Use MockBukkit JUnit test and produce calls to AWS as a side effect. They look like Unit Test, but don't serve this purpose.
• Use a custom python script to verify that the lambdas stored the correct data in s3/dynamodb.
• Keep test data from AWS

Integration Test: AWS -> Live Frontend

• Reuse test data from other Integration Test
• Use Cypress and visit test-specific challenges and perform validation on them.
• Clear test data from AWS
