fix(kopiaui): Add timeout in pollOnce https.request equal to poll interval

[riedel]

was meant to fix #2453 (which I cannot reproduce with the current server part)

[riedel]

While this PR certainly can make sense IMHO i am not sure if it fixes #2453 or something else fixed it already, because I tried to recreate the problem with the latest source code without success (reverting this PR on my local code base).

To trigger the problem I IMHO one needs to get the server into a hanging state, which I could not: it returned 500s and some other errors now. However, the errors returned seem to be non-consistent, when I try to trigger them. I onl get y

(node:24124) electron: Failed to load URL: https://127.0.0.1:52703/api/v1/objects/7ae6d461baed99571532608ced577d62?fname=config with error: ERR_HTTP2_PROTOCOL_ERROR 

followed by (now instead of the hanging socket, I suspected):

11:51:02.417 > error fetching status Internal Server Error 
11:51:04.347 > error fetching status Internal Server Error 
11:51:07.351 > error fetching status Internal Server Error

Still: I think the PR make sense, so I mark it as ready.

Managed to reproduce the bug and this is not the non-timeouting socket.

i think this still makes sense to merge, even if it's not a complete fix.

Along with #3666 this should fix the socket exhaustion issue.
