Add support for query parameters for line items LTI 1.3 AGS 2.0
Description
This will support filtering lineitems by parameters:
lti_link_id - limit the line items returned to only those which have been associated with the specified tool platform's lti link ID
tag - limit the line items returned to only those which have been associated with the specified tag
resource_id - limit the line items returned to only those which have been associated with the specified tool resource ID
This is optional in the spec but since Sakai's gradebook service conveniently gives me a place to store this stuff I can implement it. This could be slightly more elegant if SAK-40687 were implemented but I can make it work by overloading the EXTERNAL_ID a bit
