[syft-rds] e2e test for the new syftbox client

[khoaguin]

Description

So far, we have been doing:

1. Develop code and examples in syft_flwr or syft_rds
2. Test locally with rds's stack = setup_rds_server and stack.init_session. This set up a shared SyftBox folder (without any syncing) to test things out locally. We can't test things like sync permission with this approach
3. Then set up different machines to test things out using the new syftbox

Goal: Set up a the e2e in rds that uses the new syftbox client (set up a local syftbox server and several clients), so with any new changes in rds, we will have it run automatically to make sure that things still work. For example, with the new permissions PRs in syft-extras and rds,

• New perms format and filename for RPC syft-extras#40
• Fix perms for RDS Store syft-data-science#79

it makes rds's e2e test fail, since the new permission would work with the new syftbox client, but fail for the old one

Quick fix:

• Manually create the new permissions
