WIP ♻️ storage tests refactoring

[pcrespov]

What do these changes do?

Upgrades storage service folder structure

• updates test folder
• updates tests fixtures
• update reqs: see requires.io
• deprecate s3wrapper ( separate PR Refactoring storage: removed s3wrapper #2295 )
• upgrades service dependencies
• disables blackfynn and removes dependencies
• deprecate storage_sdk? ? -> Only used in node-ports. Basically node-ports is an sdk on top of storage and the pg db. The latter should be avoided.
• resolve urllib3 constraint due to aioboto!
• remove attrs

• Implements part of storage refactoring backlog #2396

How to test

cd services/storage
make install-dev
make info
