add missing shared config for clientIpHeader

[ida613]

What does this PR do?

clientIpHeader was missing from shared config, meaning that users couldn't remap the client IP header to the http.client_ip span tag. This PR adds the shared config and adds test cases for the config itself along with test cases within the http plugin to ensure functionality works as intended.

is the misspelling intended here ?

i'm not sure why you're changing the koa plugin tests ? ipHeader is not a koa or web framework thing. It's used directly in the web.js file, so the http plugin. Why is it tested here ?

[rochdev]

Looks like the PR was merged despite your comment. I agree it probably makes more sense to have an http test for this, but since all web frameworks inherit the http span anyway I guess any integration works. Since it's now merged, I personally am not too worried, but if you really think it should be moved to http that can be done as a follow-up PR.

[simon-id]

It's alright. It would have just been better to have a comment to explain this to the future maintainer of this file
