Standardise currency pair in metric labels

[bowd]

Expected Behavior

Prometheus metrics that are segmented by currencyPair should have a consistent label. Specifically:

currencyPair: "CELOUSD" | "CELOEUR" | "CELOBTC"

Current Behavior

We have two ways of labelling metrics:

pair: "CELO/USD" | "CELO/EUR" | "CELO/BTC"
currencyPair: "CELOUSD" | "CELOEUR" | "CELOBTC"

Having this duplications makes it harder to leverage dashboard-wide filters in a smart way.

Reason for need: Consistent dashboards for stablecoins are a bit difficult to create at this time. Reporting is harder to scale.

Does this include redeployment or changing any metrics/dashboards?

[bowd]

I think the metrics/dashboards should be included but I'm starting to think we need a new way of dealing with deployments, cose I also have this questions for every task. Maybe it's time to come up with a deployment schedule for oracles. This is outside the scope of this conversation but we could setup a schedule where we upgrade Alfajores -> Baklava -> Mainnet consistently with a certain cadence so we can separate the deployment question from features :-/

But yeah for this I'd say we should take into account both deployment and updating the dashboards.
