[subgraph] configurable history pruning

[kasparkallas]

Why?

We want to index subgraphs to Goldsky with less entities created in the database.

How?

To do so, we will indroduce history pruning.

Other

Updated subgraph tooling and spec.

Warning!

If you rely on time-travel queries then this will be a breaking change. Contact us if you need continued access to time-travel queries!

Example of a time-travel query:

{
  challenges(block: { number: 8000000 }) {
    challenger
    outcome
    application {
      id
    }
  }
}
