Goal
Provide a mechanism so that anyone can close stale allocations.
Motivation
Stale allocations affect the stability of the network when an indexer that has a big proportional allocated stake on a subgraph does not keep it active, as other indexer won't want to allocate if it already has a big allocation. Stale allocation also reduce the speed of how value flows through the protocol, reducing the frequency at which curators and delegators get their share of rewards/fees.
Currently delegators for an indexer are the only one that can close them, but this is an unnecessary validation considering that anyone could turn into a delegator, even with the smallest amount of tokens, and then close it.
