T979: Allow spaces in wireguard interface descrs
Previous to this commit, setting a Wireguard interface description would
result in a validation error similar to the following:
brooks@border# set interfaces wireguard wg0 description "Tunnel" [edit] brooks@border# set interfaces wireguard wg0 description "Tunnel tunnel tunnel" interface description is too long (limit 100 characters) Value validation failed Set failed [edit]
This commit makes the regex less restrictive up to 100 characters.
