Changing milestone.

I have an idea to build this feature into the indexer, much like our "missing block recovery" mechanism. We would provide two CLI args --block-fetching-exe PATH and --block-fetching-threshold N where PATH is the path to the "block fetching" mechanism executable (essentially, a script that takes a block height arg) and N is time in sec. Operation would go as follows:

• add another condition to the indexer work loop: check the best block is not "too old" (determined by N and current time)
• if the best block is too old, run the block fecthing exe provided with the arg best_tip.blockchain_length + 1

Closing as we don't feel this is necessary
