Add config and state for individual Ethernet port priority in a LAG (o…

…penconfig#943)

* add config container to LACP aggregate interface member

Add config container for LACP aggregate interface member with port-priority
and interface. Change /lacp/interfaces/interface/members/member/interface to
point to the new leaf /lacp/interfaces/interface/members/member/config/interface.
Change /lacp/interfaces/interface/members to config true.

This change is not backwards compatible due to breaking change of changing type for list
