Description

Adding in a cache for recently used merkledag nodes will improve performance on workloads that rely on manipulating object graphs.

Ideally, the size of the cache should be configurable from the config file, and if set to default (or unset in the config) be reduced when IPFS_LOW_MEM is set.

Contributor guide

Research direction
Study the dagservice code to understand where to integrate the cache, implement a configurable cache size, and ensure it respects the IPFS LOW MEM environment variable.
