Split US and CA clients

[ibralu]

Notes:

• @fluxxu Let me try ca/us shipping first but its implemented 1:1 with docs, CA shipping doesn't seem to return proper errors its always 400 with the same message, US should work fine
• CA get released orders returns 404 even though its in spec and docs

Tasks:

• Updated all dependencies and set edition to 2021
• Separated us and ca client and some types
• Removed deprecated api calls, see below for all changes
• Changed to async
• Updated cli to account for multiple clients and use derive clap
• Changed format where applicable from JSON to XML
• Added mocked tests for each call where applicable
• Added openapi download cli, so maybe in the future we can switch to proper openapi spec, right now types are not 1:1 and schema has errors

Split us and ca clients example

api

let client = walmart_partner_api::ca::Client::new()
client.get_all_feed_statuses(walmart_partner_api::ca::GetAllFeedStatusesQuery)
client.get_all_feed_statuses(Default::default())

let client = walmart_partner_api::us::Client::new()
client.get_all_feed_statuses(Default::default())

cli

cargo run --bin cli --help
cargo run --bin cli us --help
cargo run --bin cli ca --help
cargo run --bin cli ca order ship --purchase-order-id SOMEID --line-number 1 --ship-from-country CA --ship-date-time 2022-04-19T20:27:44Z --method-code Standard --tracking-number SOMETRACKINGNUMBER                                        

Differences between current and previous version

• Removed pregenerated reports for US, they are deprecated
• Added on request reports for us, need to create request -> poll if finished -> get download url
• Removed bulk feed upload for US
• Added few extra apis
• Extended and changed some types and api inputs

Possible improvements

• Add retries
• Add spans and propagate correlation id from it to walmart

Thanks!

Add retries

Retries should be handled by s2-mod. We just need to impl fn should_retry() -> bool for error types.
