Reprojection of layers without EPSG code

[uniomni]

It appears that GeoServer will happily accept and display layers with ESRI WKT spatial references. However, when downloaded again they always come in their native projection rather than the requested projection.

We noted that these layers have Native SRS set to UNKNOWN even though a valid WKT was supplied. We also noted that one can force reprojection through the GeoServer interface, but this is not feasible if layer upload and download are done from within an application.

We stipulate that an EPSG code is needed. However, as this is not provided by ESRI, it would be better if GeoServer could derived this code from the WKT projection.

Alternatively, forced reprojection should be specified through the REST interface whenever one which is not native has been requested.
This is a major problem as ESRI layers are extremely common.

Since this cannot be fixed at the WCS level we can instead let users download the original file. This will be fixed by #1421
