chore(gas_price_service): initialize v1 metadata

[rymnc]

Note

This is PR 1/n in introducing GasPriceServiceV1 which links to v1 of the gas-price-algorithm. This PR is mainly used to start the discussion around v1 metadata and the fields we need.

Linked Issues/PRs

fixes #2286

Description

• Specifies a V1Metadata that will be stored along V0Metadata wrapped within the UpdaterMetadata struct.
• We use fallible conversions between the two, v1 => v0 should be possible, but I hope we can discuss and decide about default values for the v0 => v1 metadata migration.
• Constructor for AlgorithmUpdaterV1 from V1Metadata

Checklist

• Breaking changes are clearly marked as such in the PR description and changelog
• New behavior is reflected in tests
• The specification matches the implemented behavior (link update PR if changes are needed)

cc: @MitchTurner, if you can describe which ones we need and which ones are just being used/mutated internally by the AlgorithmUpdater please

I have the rest of the code for GasPriceServiceV1, getting them out in chunks though
