[kea-dev] same subnet design

[Francis Dupont]

We are improving the way a subnet configured twice is detected.
A design document is available for information and comments at:
 https://kea.isc.org/wiki/SameSubnet
To summary we should propose two modes:
 - strict checks which should detect current configuration mistake.
   It will be the default mode.

 - relexed mode where only duplicated subnet IDs give an error.
   It will be optional and require subnet IDs.
