feat(snuba): add uptime consumer deployment configuration

[TartanLeGrand]

This pull request introduces a significant update to the Sentry Helm charts, primarily focusing on renaming and restructuring components related to "subscription-consumer-results-eap-items" and introducing new configurations for "uptime-results" and "uptime-consumer." The changes aim to improve clarity, consistency, and functionality in deployment configurations.

Renaming and Refactoring Subscription Consumer:

• The file deployment-sentry-subscription-results-eap-items.yaml was renamed to deployment-sentry-uptime-results.yaml, and all references to subscriptionConsumerResultsEapItems were replaced with uptimeResults in the deployment configuration. This includes updates to fields such as replicas, annotations, podLabels, affinity, nodeSelector, tolerations, volumes, and securityContext. [1] [2] [3] [4] [5]

• The service account file serviceaccount-sentry-subscription-results-eap-items.yaml was renamed to serviceaccount-sentry-uptime-results.yaml, with corresponding updates to the service account naming and enabling conditions.

Addition of Snuba Uptime Consumer:

• A new deployment configuration for the Snuba uptime consumer was added in deployment-snuba-uptime-consumer.yaml. This includes support for configurable replicas, environment variables, resource limits, liveness probes, and other deployment settings.

Updates to Values Configuration:

• In values.yaml, the subscriptionConsumerResultsEapItems section was replaced with uptimeResults, and a new uptimeConsumer section was added under the snuba configuration. These changes introduce default settings for replicas, liveness probes, and other deployment parameters. [1] [2]

Could you rename your PR to feat(snuba)!: add uptime consumer deployment configuration

It's a breaking change

We also need the documentation on upgrade notes. Thanks!

Why it's a breaking change ? No migrations have touch, no data loss, no api loss 🤔

[Mokto]

You've changed the way values are used (and it's much nicer!) so people need to know in case they were using them.
