[Med] This is to simplify the validation checks when a certain address family 
is needed. Think about simple things such as the following: 

  grouping ipv4-allocation-type:
    +-- prefix-length?             uint8
    +-- address-allocation-type?   identityref
  grouping ipv6-allocation-type:
    +-- prefix-length?             uint8
    +-- address-allocation-type?   Identityref

When we dive into the structure, we will see that we have distinct prefix 
ranges and specific types for each AF. All these checks are done using 
appropriate YANG statements (e.g., to prevent that slaac is provided for an 
IPv4 context). If we want to reason about a common structure for all address 
families, then we will need to have a knob of the address family at the first 
place and then have checks as a function of the address family, with 
complicates things.
