[pve-devel] [RFC PATCH http-server 2/2] use HTTP_INTERNAL_SERVER_ERROR were appropriate instead of '501'

[Dominik Csapak]

The http status code 501 is meant to be 'Not Implemented'[0] but that
clearly does not fit here as the default error when we encounter a
problem during handling an api request or upload.

So instead use '500' (HTTP_INTERNAL_SERVER_ERROR) which we already use
in other places where it fits.
