Diagnostics Corefiles

The tolt diagnostics corefiles portion of the tree is utilized for management of corefiles on the system.  It allows for the creation of corefile archives that can be used by Tellabs Development to determine the cause of failures in the system.

There are three actions, a list to list the corefiles present on the OLT, a create action to create a corefile archive to sending to tellabs tac, and a delete action for deleting unneeded core files.
