Misuse of get_all_rs in E2E Test

[filipcirtog]

Summary

While working on this PR, it was discovered that the test multi_cluster_reconcile_races.py incorrectly asserted that get_all_rs (replica sets) runs for all MongoDB resource types, including MongoDBMulti, Sharded, and Standalone. This behavior is a bug.

This PR resolves the issue by ensuring that get_all_rs is only used to test replica set creation. Additionally, get_all_mdbmc, get_all_sharded, and get_all_standalone are now used to verify the creation and behavior of MongoDBMulti, Sharded, and Standalone resources.

However, during testing, it was observed that MongoDBMulti resources are not transitioning to the running stage due to the following error:

{"logType":"agent-launcher-script","contents":"Using Kubernetes CA file"}
{"logType":"agent-launcher-script","contents":"Created symlink: /data/journal -> /journal"}
{"logType":"agent-launcher-script","contents":"Downloading Agent version: latest"}
