## What changes were proposed in this pull request? Due to the high cost of creating and initializing Mac instances, S3 token validation can be a bottleneck in OM latencies for S3 use cases. ``` Mac mac = Mac.getInstance(HMAC_SHA256_ALGORITHM); mac.init(signingKey); ``` <img width="1711" alt="Screen Shot 2023-03-13 at 11 33 35 AM" src="https://user-images.githubusercontent.com/46785609/226329642-35954efd-7052-4ea6-b314-c5971aff51f5.png";> Caching Mac instances in ThreadLocal (as they are stateful) and reusing them eliminates the need to create and initialize these objects from scratch, mitigating the high cost of S3 token validation and significantly reducing overhead while improving overall performance. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-8154 ## How was this patch tested?
