Subject: T8910: ipoe-server: expose accel-ppp idle-timeout option

Add a CLI knob to terminate idle IPoE sessions after a configurable
timeout:

  set service ipoe-server idle-timeout <0-86400>

Today there is no way to age out stale IPoE sessions: clients that go
silent (powered off, link down) leave a session record on the router
indefinitely. accel-ppp natively supports idle-timeout in its [ipoe]
section but VyOS did not expose it.

The option is added as a shared accel-ppp include so it can be reused
by other accel-ppp services in follow-up PRs.
