[MapProxy] How to check if the defined cache is being used

[Travis Kirstine]

When configuring the layer the source needs to point to the WMS cache (it
probably does).  I think if you start the development server in debug mode
it will show the backend requests to the cache.  Alternatively if you want
to "proxy" your WMS server you can use something like tagged sources.  I
find this works better for WMS users as you get better quality images and
can support multiple SRSs.
