For long running node installs show a message

[hardillb]

Current Behavior

If a node install takes a long time the UI just returns to the list of nodes in the catalogue and allows the currently installing node button to be pressed again.

Expected Behavior

The UI should show a message saying the install will continue in the background at the the node will be added to a palette once complete.

Installing other (or attempting to install the same node again) nodes should be blocked until the first completes

Steps To Reproduce

On a slow machine (limited memory and CPU resources) install a large node e.g openapi-red and wait

Example flow

NA

Environment

• Node-RED version: 3.1.7
• Node.js version: 18.x
• npm version: 9.x
• Platform/OS: All
• Browser: NA

Should this move to using the editor messaging API rather than wait on a long HTTP request to return (or time out in this case?

It already updates the UI when/if the install completes cleanly, just not if it fails.

OK, so the timeout is actually coming from the reverse proxy, Standalone Node-RED doesn't timeout it waits forever.

Question now is do we extend the reverse proxy timeout or still try and handle this better in Node-RED?
