NC | Service + CLI | Internal Refactoring and renaming

[romayalon]

Environment info

• NooBaa Version: Master
• Platform: NC

Actual behavior

1. Recently, in NSFS | NC | Removal of NSFS prefix from user facing components - service, cli, configs and events  #7989, we did the external renaming of nsfs service and manage_nsfs CLI, we need to pursue this change and apply internal renaming as well.
2. manage_nsfs -> cli
3. nsfs.service -> noobaa.service
4. noobaa.service - execute the endpoint.js instead of nsfs.js
5. endpoint.js - adopt nsfs.js code - check per platform which sdk it should init, and other nsfs.js features.
6. nsfs.js - remove non SimpleFS stuff + rename.

Expected behavior

1. nsfs service and manage_nsfs CLI are renamed internally to noobaa service and noobaa-cli.
