The current profile inputs/outputs do not have meaningful IDs
(e.g. i1, i2, o1) and are not used by the client so they should
not be displayed in the CLI output.
In the future the IDs should be renamed into something meaningful
(e.g. keygen, sn, cert) and the inputs/outputs should be retrieved
by ID. New methods have been added to retrieve by ID.
