We 'preload' most CIDs we interact with on the network. In some cases this can mean preloading the same CID over and over again which is not necessary. This PR adds a LRU cache to the preloader with a default size of 1000. The cache is used to avoid re-preloading the same CID over and over again until it drops out of the cache. We use a cache that will evict CIDs over time to have some sort of upper bound on memory usage. Fixes #3307
