Add 'id:' and 'do:' routes to support legacy bookmarks

Issue

In legacy CRDL, we have item/collection bookmarks that look like this:

• Bookmark: http://crdl.usg.edu/id:nps_mlk
• Bookmark: http://crdl.usg.edu/id:kdl_abrad_19891111tachau

In new CRDL, we need to add an id: route to support these. id: is followed by item or collection record_id

This route can redirect to the record route, e.g.,

http://crdl.usg.edu/id:kdl_abrad_19891111tachau

can redirect to

https://crdl-bl-staging.galib.uga.edu/record/kdl_abrad_19891111tachau

Also, the collection link

http://crdl.usg.edu/id:nps_mlk

can similarly redirect to

https://crdl-bl-staging.galib.uga.edu/record/nps_mlk

since we show both items and collections in the record route.
