Previously if subscriber was automatically created it got assigned
random MSISDN number between 20000 and 49999. Make it
optional (defaulting to previous behavior) by adding following:
* optional "no-extension" argument to subscriber-create-on-demand
* db unit tests
* vty test
The range for random extension can now be specified with
"subscriber-create-on-demand random" command.
Note: using the db made with new code might result in subscribers with
empty extension. Such subscribers cannot be deleted using old
code. Make sure not to mix db versions or manually fix it by editing
sqlite with external program.
Fixes: OS#1658
