[enhancement]: Provide update self-hosted agent only Proxy parameter

[kkbruce]

Describe your feature request here

We need a Proxy on our intranet to update the self-hosted agent automatically. Like this:

.\config --proxyurl http://proxy:port --proxyusername "xxx" --proxypassword "yyy"

However, we found that after setting up the Proxy, although the automatic update usually works, the original regular release operation for the intranet will become an error of being unable to find the domain location. Can the self-hosted agent have an independent parameter only provided for the automatic update of the self-hosted agent instead of being applied universally, which will affect the original call for the local scheduling task?

Like provide --updateagentproxyurl parameter:

.\config --updateagentproxyurl http://proxy:port --proxyusername "xxx" --proxypassword "yyy"

It was our mistake. We found that we gave the wrong account, which caused the error caused by insufficient permissions.
