Retry for network changes on localhost

[edlerd]

Done

• requests to alter networks on localhost will fail, add retry logic for those cases. The problem only occurs when talking directly to lxd (without dev server) on localhost via https://localhost:8443/ui/

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 @lorumic or @edlerd for access.
   • With a local copy of this branch, run as described here.
2. Perform the following QA steps:
   • check network editing/renaming/creation/deletion
   • the error can only be triggered when talking directly to LXD on localhost (without the dev server), maybe not worth to find a way to set this up, we can verify the fix from the nightly LXD build after it is merged.

The fix makes sense, and I expect it to work even if I cannot test it, but it's a somewhat ugly workaround. Do we have an idea of what is the root cause of this problem? How was this found? Might be worth discussing it with the core team?

I will approve, but I still suggest to consider what I wrote in the previous comment:

Well done, thanks!

Merged as upstream has a hard time finding a fix and we want the UI to be without this bug.
