Subject: T7348: Add config CPU thread-count for accel-ppp services

Accel-ppp services should not use all CPU cores to process requests.
At the moment accel-ppp services use all available CPU cores
to process requests from the subscribers (establish/update session/etc).
During mass connection of sessions, this can lead to the fact that it
utilizes all CPU, and for other services like FRR, there is not enough
CPU time to process their own stable work.

services:
 - L2TP
 - SSTP
 - PPPoE
 - IPoE
 - PPtP

Add this option configurable and use all cores if not set:

```
set service pppoe-server thread-count < all | half | x >
```
The defaultValue `all`
