feat: import strategy - sales channels support (#2124)

**What**
- add support for specifying sales channel with import strategy
- additional:
  - refactor SC service to use `retrieve_` pattern
  - fix: pass arguments from `startServerWithEnvironment` to setup server
  - fix: minio undefined resolve/reject calls
  - fix: csv parser - detect missing columns from schema only if the column is required

**How**
- extending schema to expect sales channels columns in an import CSV file
