Revert "Implement the Delete interface"

This reverts commit 433beadcb8b0af4ebdc05e2b46be0be0ac3085e6.

As objects will be deleted on phosphor-logging interfaces removed
signals, the Delete interface is no longer required.

Tested: Ensure the REST Delete calls still work via the
        InterfacesRemoved handler.
