WIP: Added support for USD based price oracle

[juanmardefago]

This changes should fix the PriceOracle breaking changes introduced in block 10678764, adding USD based underlying price calculations. Currently indexing on a dev subgraph to test this.

Let me know when the syncing is done so we can see it working!

Currently at 86.8%, unfortunately this subgraph is quite slow to index :(

[juanmardefago]

Currently at 92,7%.

Most likely will be fully indexed within the weekend

@davekaj Fully indexed now, underlying price in ETH seems to be working ok now ;)

Also quick heads up @davekaj, last PR we merged required a restart of the wrapper service for the compound v2 subgraph, otherwise the subgraph wouldn't get properly updated (specially the schema). In this case we didn't modify the schema, but it still would probably be better if the wrapper gets restarted anyways

[davekay100]

Ah good point, i will look into this before me merge it

[davekay100]

Yep we will do the restart
