Add early rejection from RestHandler for unauthorized requests (#3418)
Browse files Browse the repository at this point in the history
Previously unauthorized requests were fully processed and rejected once
they reached the RestHandler. This allocations more memory and resources
for these requests that might not be useful if they are already detected
as unauthorized. Using the headerVerifer and decompressor customization
from [1], perform an early authorization check when only the headers are
available, save an 'early response' for transmission and do not perform
the decompression on the request to speed up closing out the connection.

- Resolves opensearch-project/OpenSearch#10260
