Subject: T5704: PPPoE L2TP SSTP IPoE add option max-concurrent-sessions

Add `max-starting` option:

  [common]
  max-starting=N

Specifies maximum concurrent session attempts which server may processed

  set service pppoe-server max-concurrent-sessions '30'

Useful to prevent high CPU utilization and compat execution
scripts per time.

(cherry picked from commit 47645f9d0243ce48a473ab7f8cdbd22c19f69f28)
