[Hawkular-dev] Metric id and url restrictions

[Matt Wringe]

A couple of points here:

1) I agree that its not an issue with our code here. Its a problem that 
exists in other third party intermediary servers which are not compliant.

2) I agree that the POST hack instead of GET could be seen as being 
against the REST principals, but its still REST compliant (POST is still 
unsafe and idempotent. It could be seen still as creating a new resource 
which is returned but not stored on the server). It might not be the 
most performant thing to use since caching servers are out of the 
question. Its what is currently used in InfluxDB as a way to get around 
this issue.

This is not just an issue with the Kubernetes proxy, its also an issue 
with EAP, other web server, other apache components (or at least some 
older versions), and apparently a bunch of other proxies servers out 
there. Its a common enough problem in this space that we have already 
ran into in two places when dealing with OpenShift integration work.

I don't think its acceptable to say that since we are compliant, its not 
our fault and we wont to anything to help get anyone get around this 
issue. We need to work in the real world and this means having to 
(potentially) deal with the common problems which exist out there.

For now, it looks like we are just going to disable certain checks in 
EAP to bypass the error there and try and patch the kubernetes proxy to 
get around the issue.

Hopefully this will be enough for now and that we don't run into other 
issues in the near future. But we may want to consider making things 
easier when we know this is a potential problem area.
