Currently we're using the `DEFAULT_PALM_CACHE_SIZE_MB` in disagg config for PALM and that's causing `test_error_info02 and `test_cache_evict_config02` to fail.

We should increase this limit either in the config inside `helper_disagg.py` or increasing the default cache size mb to 2GB.

Scope:

Increase the cache size to 2GB for hook_disagg.py
Rerun all the failing python tests to see if tests pass, if they do we allow them to run instead of being skipped.
