[FSTORE-1793] Logger messages increasing latency for during fetching feature vectors.

[manu-sj]

The PR fixes an issue in which a increase in latency was observed during fetching feature vectors.

Root Cause:
The function handle_rdrs_feature_store_response was taking a CPU because the logger message was getting created even if the message was not printed.

Fix Done
Add if conditions to check the logger messages before it is printed.
