No longer able to assign a /31 address on Wireguard interface
Closed, ResolvedPublicBUG

Description

[edit interfaces wireguard wg1]
vyos@vyos# set address 10.255.249.0/31

  Invalid value
  Value validation failed
  Set failed

This worked on the 1.2.0-rolling+201812110337 build, but no longer works with the 1.2.0-rolling+201905170337 build.

I expect there's nothing but a simple validation variable that needs to be adjusted, but I wouldn't know where to look. As for the functionality of it, I had communication over the tunnel using addresses in a /31 block before, so there's no reason for it to be prevented now..
