[Feature] Permissioned Retrieval M1

[xinaxu]

Business Need

Aggregators require that their customers’ data stored on Filecoin not be retrievable by anyone else.

Requirements

As a Motion user, only I must be able to retrieve an object I store from a given Filecoin SP.

Implementation Plan

• Object or bucket level ACL is out of scope
• Design: [Boost Retrieval ACL](https://www.notion.so/Boost-Retrieval-ACL-296c677505de42f291e4b695f16f1e3b?pvs=21)

### Tasks
- [ ] Authentication Service on SP side
- [ ] Integrate with Authentication Library for Auth token generation
- [ ] Test Permissioned Retrieval with real SP
