### What changes were proposed in this pull request?
Minor fix the v1 RESTful apis before 0.6.0 release.
1. update the API description to use UPPER case worker EventType
2. `subResourceConsumption` => `subResourceConsumptions`.
### Why are the changes needed?
1. With https://github.com/apache/celeborn/pull/2754, the openapi-sdk works well. but for the RESTful call without SDK, the worker eventType is still case sensitive, might be caused by the jersey issue mentioned in https://github.com/eclipse-ee4j/jersey/issues/5288. So, In this PR, I change the description in the swagger for user guidance.

2. rename `subResourceConsumption` to `subResourceConsumptions`.
### Does this PR introduce _any_ user-facing change?
No, the api has not been released.
### How was this patch tested?
GA.
