Merge version 1.4.1 into main

[bhaskarkishore]

Version 1.4.1 contains fixes and some enhancements:

• Fixed resizing failing for very large images.
• Fixed moderation failing when image file size is very close to Rekognition imposed limits.
• Fixed a bug where in moderation reporting was incorrect.
• Fixed missing metrics moderation_hit by re-adding it.
• Added missing Jemallocator runtime config. The proxy will release memory more aggressively now.
• Added a caching layer to store moderation results from the database. This should speed up response time for cached content.
• Added new metrics for capturing usage of the following features: image resizing, the database cache, ipfs fallback gateway, and moderation categories.
• Generally Improved logging
