Create IPFS Driver

[fritzsima]

Currently the GAIA Storage System supports the following drivers:

• Azure
• AWS
• GCP
• Dropbox
• Localdisk

Analogically to those, implement a driver for IPFS, so Users can store their data on IPFS using the GAIA Storage System.

Subtasks:

• [x] Implement IPFS driver module
• [x] Update admin module for IPFS driver
• [x] Update hub module for IPFS driver
• [ ] Update reader module for IPFS driver

If @fritzsima will no longer be working on this, I'm merging the on-going work to the branch feature/add-ipfs-driver. Continuation of this work should be done on that branch. @bjorger
