Log file should use the domainname instead of the arbitrary creation id

[MathijsG]

Currently if you wanna dive into the logs of a certain proxy, you need to go to the log folder and access for example proxy-host-12_error.log or proxy-host-12_access.log. This number 12 comes from the id that the proxy instance is. Which to me is a very arbitrary and hard to spot number. You can only subtly see it if you click on the 3 dots on a proxy, and see the text "Proxy Host #number" there.

I would propose a more semantic name or id that will be used in the logs. For example the domain name, would need much less lookup all the time. Or an added ability that you can give a proxy host a certain name, that is being used for the logs.

What do you guys think? :)
