Bug Description: a special index type "subtree" is introduced for
entryrdn.  The DS Console does not spport the index type, and
the index page issues an error "unkown index type<subtree>".
Fix Description: The index type is special and is available only
for entryrdn.  Also, entryrdn cannot have any other index type(s).
Thus, there is no much benefit to show the index type on the index
page on Console.  This patch skips showing entryrdn index name and
the subtree index type.
