[eth] Gas improvement: Increase optimizer runs to 10000 (#390)

* [eth]: Gas improvement: Increase optimizer runs to 1_000_000
Increasing optimizer runs will optimize the gas usage of methods more and will increase the contract size, hence the deployment cost.

Snapshot difference:
```
testBenchmarkGetUpdateFee() (gas: -101 (-0.076%))
testBenchmarkUpdatePriceFeedsIfNecessaryNotFresh() (gas: -334 (-0.189%))
testBenchmarkUpdatePriceFeedsNotFresh() (gas: -1312 (-0.416%))
testBenchmarkUpdatePriceFeedsIfNecessaryFresh() (gas: -1626 (-0.430%))
testBenchmarkUpdatePriceFeedsFresh() (gas: -1576 (-0.441%))
testBenchmarkGetPrice() (gas: -259 (-0.969%))
```

p.s: I read one place that `runs` is an estimate of how many times the contract is expected to be called as opposed to number of optimization passes through the code!
