Use fetch all volumes endpoint

[edlerd]

Done

• use fetch all volumes endpoint
• we used to fetch all storage pools and then all volumes for each pool, with List all storage volumes via API lxd#12550 a new endpoint to directly fetch all storage volumes is available, this PR is starting to use it.
• This only works with the latest/edge version of lxd

QA

1. Run the LXD-UI:
   • On the demo server via the link posted by @webteam-app below. This is only available for PRs created by collaborators of the repo. Ask @mas-who or @edlerd for access.
   • With a local copy of this branch, run as described here.
2. Perform the following QA steps:
   • ensure storages -> volumes page is working as before

Interesting observation:

old way of getting volumes:

new way of getting volumes:

The new way of fetching volumes actually resulted in longer response time from server, this is due to the old way of fetching volumes sends concurrent requests to the server. I think it's still better since we are not overloading the server.

QA looks good, just one small change for code 🙂
