Missing <ows:Title> and <ows:Abstract> elements in WCS GetCapabilities response

[jfbourgon]

Those layer descriptors are optional but are already defined in layers description inside the service configuration and would help the layer discovery in GIS tools such as QGIS.

layers = {
   hrdtm = {
        type = "simplesourceconf"
        name = "hrdtm"
        title = "High Resolution Digital Terain Model (HRDTM)"
        abstract = "High Resolution Digital Terain Model generated from LiDAR"
        source = {
            ...

With ows:Title and ows:Abstract missing, layers appear as unamed in QGIS menu
