feat: Support sync test connection API tokens (#135)

Similar to #109

Testing a connection is very similar to running a sync job, just with a different CLI command and permissions.
It needs an API token to be able to download plugins and update the status of the test (it won't have access to update usage and progress line sync run API tokens)
