SetConfig optimization + billing config improvements #36

These are now settable via setBilling but can also be nil to use the built-in default

+    let gas_adjustment = Decimal::percent(u64::from(config.gas_adjustment.unwrap_or(140)));


Adjusted based on devnet values. We seemed to over-estimate by almost exactly 4x. The amount charged is also the "gas allocated", not "gas used" and the difference seems to be about 1.4x

    pub observation_payment: u64,

+    pub base_gas: Option<u64>,


I'd suggest we rename this as gas_base to be consistent with other args.

Should we rename this attribute as recommended_gas_price_uluna to keep it consistent?

Consider extracting this scale factor 10u128.pow(9) as a constant.

@archseer There are two more places signers are handled as <Vec<Vec> still:

That's converting/unwrapping from the Binary type, internally we just use byte vecs https://github.com/smartcontractkit/chainlink-terra/blob/c5e735e9fae73580d330bfde74db64c11bcf9a39/contracts/ocr2/src/msg.rs#L30-L32

+      recommended_gas_price_uluna: input.recommendedGasPriceUluna


This should be of Decimal type (https://github.com/smartcontractkit/chainlink-terra/pull/36/files#diff-7593d1da79e988b58adce267ba96df185c0abebbfc17323f0de5e749e6419134R56)

@archseer Which format should we be applying here?

It's a string, you can pass through the value from https://fcd.terra.dev/v1/txs/gas_prices without modifying it

This info comes from the RDD, so we can expect it to come in the right format

This is so we can fit more data into the 4kb payload

If this works, I think it will have the effect of converting the decimal to an integer, either by truncating or rounding I suppose. Is that really what we want to do?

From: https://github.com/indutny/bn.js/
"Note: decimals are not supported in this library."

Ah, agreed. RDD should store this as a string to avoid losing precision. @RodrigoAD

You're completely right. I'll open a fix

Looks like it's handled in #76
