Add UI page to describe data shape for shapeless connectors

UXD has designed an extra page for shapeless connectors in #1194. Shapeless connectors are identified as ones with input/output shape or both of the form:

            "inputDataShape": {
              "type": "*"
            },
            "outputDataShape": {
              "type": "*"
            }

UI needs to add page to allow user to specify input and output shapes from json/xml schema or instance documents.

What we agreed on:

• replace No Type and Any Type with Don’t specify type
• remove Java type
• rename Select Schema Type label to Select type
• rename Schema label to Definition
• when Don’t specify type is selected other fields are grayed out
