VOL-1330: Fix bug in table based ME and Ready only attribute

Tables must be sent a row at a time
to fit in an omci payload. Also each
row needs the same key set since omci
table ops are additive.

Also fix bug where PPTP Ethernet entity
type has operational status set as writable,
which it is not per the spec.  This being
falsely writable caused reconciliation to attempt
to set oper status along with admin state,
causing the onu to reject the entire message.

Both of these caused reconciliation to never finish.
