Migrate autopilot native price estimation config from CLI args to config file

[jmg-duarte]

Description

Move native price estimator settings (estimators, api_estimators, results_required, cache_refresh_interval, native_price_prefetch_time) from CLI arguments to the TOML config file.

Changes

• Move the autopilot native price estimator settings
• Add tests

Migration Guide

Autopilot native price estimator CLI arguments have been moved to the TOML config file under the [native-price-estimation] table.

Estimator format

Previously, estimator variants were specified as |-separated strings. Now they are inline tables with a type field:

Old (CLI)	New (TOML)
CoinGecko	{ type = "CoinGecko" }
OneInchSpotPriceApi	{ type = "OneInchSpotPriceApi" }
Driver|solver1|http://localhost:8080	{ type = "Driver", name = "solver1", url = "http://localhost:8080" }
Forwarder|http://localhost:12088	{ type = "Forwarder", url = "http://localhost:12088" }

Stages (previously separated by ;) become separate inner arrays. Estimators within a stage (previously separated by ,) are elements of the same inner array.

Old (CLI):

CoinGecko,OneInchSpotPriceApi;Driver|solver1|http://localhost:8080;Forwarder|http://localhost:12088

New (TOML):

[native-price-estimation]
estimators = [
    [{ type = "CoinGecko" }, { type = "OneInchSpotPriceApi" }],
    [{ type = "Driver", name = "solver1", url = "http://localhost:8080" }],
    [{ type = "Forwarder", url = "http://localhost:12088" }],
]

Arguments

• --native-price-estimators (CLI) / NATIVE_PRICE_ESTIMATORS (env):

[native-price-estimation]
estimators = []

• --api-native-price-estimators (CLI) / API_NATIVE_PRICE_ESTIMATORS (env):

[native-price-estimation]
api-estimators = []

• --native-price-estimation-results-required (CLI) / NATIVE_PRICE_ESTIMATION_RESULTS_REQUIRED (env):

[native-price-estimation]
results-required = 2

• --native-price-cache-refresh (CLI) / NATIVE_PRICE_CACHE_REFRESH (env):

[native-price-estimation]
cache-refresh-interval = "1s"

• --native-price-prefetch-time (CLI) / NATIVE_PRICE_PREFETCH_TIME (env):

[native-price-estimation]
prefetch-time = "80s"

Code Review

The pull request successfully migrates the autopilot's native price estimation settings from CLI arguments to the TOML configuration file. This change improves configuration management by grouping related parameters (estimators, API estimators, results required, cache refresh interval, and prefetch time) within the native-price-estimation section of the config. The migration preserves existing logic, maintains sensible defaults, and includes comprehensive updates to the E2E test suite to reflect the new configuration structure. No critical issues were found during the review.

Just minor nits.

Actually left another comment on the format when I saw it fully in the services PR here. Given that the full format wasn't really easily visible in this PR I wonder if the next step should be to introduce another test that deserializes an example config with all formats inside. That way we have a reference that at least has the possibility to stay up-to-date and new formats that get introduced are easier to spot.

Let's add a migration guide entry to this PR:

Migration Guide

Autopilot native price estimator cli arguments have been moved to the TOML config file, under the table `[native-price-estimation]:
The following CLI arguments

• --native-price-estimators (cli), NATIVE_PRICE_ESTIMATORS (env), becomes:

[native-price-estimation]
estimators = []

Important note, the values for specific estimator were previously separated by |, now they have to be constructed as inline tables:
Driver|solver1|http://localhost:8000 becomes: { Driver = { name = "solver1", url = "http://localhost:8000" } }

• --api-native-price-estimators (cli), API_NATIVE_PRICE_ESTIMATORS (env), becomes:

[native-price-estimation]
api-estimators = []

• --native-price-estimation-results-required (cli), NATIVE_PRICE_ESTIMATION_RESULTS_REQUIRED (env), becomes:

[native-price-estimation]
results-required = 

• --native-price-cache-refresh (cli), NATIVE_PRICE_CACHE_REFRESH (env), becomes:

[native-price-estimation]
cache-refresh-interval = 

• --native-price-prefetch-time (cli), NATIVE_PRICE_PREFETCH_TIME (env), becomes:
