charts/wire-ingress: remove query param from logs

[jschaul]

Part of WPB-27370

When using the wire-ingress provided EnvoyProxy, ensure the request path's query string is removed from the logs, to ensure access_tokens passed as query string are not logged. Browsers are required to pass them on a query string on some endpoints such as /await.

This PR entirely removes query strings. Other options could include only sanitizing access tokens (as done in ingress-nginx) but not other query parameters.

• Check if sanitizing only access tokens (instead of removing all query param) could work (and how)
• add a (possibly manual) test (and docs) showing before/after this PR to show this acutally works as expected
