WPS: allowedValues and defaultValue support for WPS Input LiteralData

[sppigot]

For any literal input a WPS can specify a list of allowed values as a range or as a list of values e.g.

''''

ows:IdentifierKeelDepth</ows:Identifier>
ows:TitleKeel Depth</ows:Title>
ows:AbstractDraft of the landing boat</ows:Abstract>

<ows:DataType ows:reference="http://www.w3.org/TR/xmlschema-2/#float">float</ows:DataType>
ows:AllowedValues
<ows:Range ows:rangeClosure="closed">
ows:MinimumValue1.0</ows:MinimumValue>
ows:MaximumValue2.0</ows:MaximumValue>
</ows:Range>
</ows:AllowedValues>
2.0


''''

TerriaJS should read and require user input to follow the allowed values (range or list) and initialise the form field with the defaultValue. Currently, if I include a WPS LiteralData Input (KeelDepth) with an AllowedValues element, TerriaJS trips an error on the browser console with the message: "The parameter KeelDepth is not a supported type of parameter."
