Allow enabling the Cost Model in other networks than mainnet
After the multi-network changes introduced in 668, the Cost Model feature was restricted to Ethereum Mainnet. We should find a way to enable this feature for other networks besides that.

If the roadblock is the availability of GRT/DAI uniswap pairs on other network, the agent should still allow using cost models when inject-dai=off.
Gathering some notes from a quick brainstorming session with @tilacog
Tasks to do
- [ ] Update code to support cost-models on each network: ensure data models include
protocolNetwork, etc... - [ ] Decide and implement network agnostic approach to fetching GRT/DAI pair price
Some initial ideas for network agnostic approaches to fetching price:
- Create a small, specific subgraph tracking the GRT/DAI or GRT/USD pairs on Uniswap (and maybe other protocols too?)
- Simply use the GRT/DAI price from Mainnet across all networks
- ....
I think that for the purpose of the cost model we could just use the data from Ethereum. What's important is that the oracle we use has enough volume.
