multi shelves model

[Infinera-OR]

I'm not sure whether there was topic for multi-shelves in past release or not. One question for the node with multi-shelves: we shall use the auto-provision shelves or operator added shelves?
If we use the auto-provision procedure, it means the slave-shelf's shelf-name were definied by the master shelf.
If we use the manul provision procedure, the operator will add the slave-shelves and the connected shelves need match the pre-configed shelf-name.

Each procedure we face one problem:
1: There is no physical tracing the slave-shelf, then when the slave-shelf connected the node couldn't match the provisioned shelf and the slave-shelf. It will affect the manul-provision procedure.
2: There is no some specific key to trace each slave-shelf. Then it will face problem when the salve-shelf replacement. System don't know it's a new shelf or a existed one. It will affect the auto-provision procedure.

One of the assumptions made by open roadm was that there would be no technician login to the NE at the site during installation.
