Description

I've run into multiple cases that got broken by IMPALA-8897. The general problem is the assumption that the hostname that the Impala server refers to itself is resolvable by the client accessing the web UI. Cases I've run into:

• In docker and kubernetes, where the internal hostnames aren't visible outside of the internal network
• On systems without a DNS-resolvable hostname, e.g. my Ubuntu desktop that I access via a static IP

I'm not sure what a fix would look like, but I think we at least need some way to work around the problem in situations like this.
