Astronomy shop fixes

[HacksonClark]

There were two issues. The first is with the deployment, it was assuming you had the helm charts locally, but I had never added it to aiopslab-applications. I first added it to aiopslab-applications, but I realized it's better if we support remote charts. So, I added a remote_chart parameter to the helm interface.

The second issue is that in the flagd config map, the faults don't match the feature flags on the website. Making that fix now.

- productCatalogFailure: Fail product catalog service on a specific product
- recommendationCacheFailure: Fail recommendation service cache
- adManualGc: Triggers full manual garbage collections in the ad service
- adHighCpu: Triggers high cpu load in the ad service
- adFailure: Fail ad service
- kafkaQueueProblems: Overloads Kafka queue while simultaneously introducing a consumer side delay leading to a lag spike
- cartFailure: Fail cart service
- paymentFailure: Fail payment service charge requests n%
- paymentUnreachable: Payment service is unavailable
- loadGeneratorFloodHomepage: Flood the frontend with a large amount of requests.
- imageSlowLoad: slow loading images in the frontend

This PR also fixes the #48?

@yinfangchen pops. I think I commented on the wrong issue.

I thought we had an issue open about astronomy shop not working? I can't seem to find it anymore, too tired :(

But this PR is a fix for astronomy shop. Basically, the install process wasn't initially set up. I also made a change to the fault injector so it restarts the pod ensuring the fault is injected, which i verified in logs and the flagd dashboard. One other issue was that the names in flagd don't match the docs, but after manually inspecting they should all be fixed.

Tested in kind as well, working great!
