Eliminate log warning "encountered non-rewritten url /404.xhtml"
Deployments on AWS seem to trigger this warning on every health check (apparently when fetching /info/?dswid=1):
Something seems to be causing a 404, which is a problem itself, but this bug is about the mishandling of that 404.
I have eliminated the unwanted logging for the moment by changing the health-check URL from /info/?dswid=1 to /info?dswid=1.
The rewrite problem with other 404s is a separate issue, but fixed by https://github.com/zanata/zanata-platform/pull/247 (coming in Zanata 4.2).
