FIx BB CI Tests To Pass Without Jaeger Label

Summary

Whenever we run MM Big Bang umbrella pipelines, the MM tests hangs looking for an s3 bucket (I think that's the issue).

To get around this, I'll add the jaeger label to the pipeline.

It would be good to have MM pipelines tests succeed without the jaeger label. Or, we should add jaeger as a test dependency of MM.

Steps to reproduce

Run a BigBang pipeline with the Mattermost label

What is the current behavior?

Cypress tests hangs / fails

What is the expected behavior?

The cypress test succeed without needing to manually add the jeager label

Relevant logs and/or screenshots

n/a

Possible fixes

• modify test to create a bucket or add timeouts/retries if MM should create the bucket
• add jaeger as a test dependency so and s3 bucket gets created
