Pull request description:
This is an implementation of #17326:
- all (currently 2) outbound block-relay-only connections (#15759) are dumped to `anchors.dat` file
- on restart a node tries to connect to the addresses from `anchors.dat`
This PR prevents a type of eclipse attack when an attacker exploits a victim node restart to force it to connect to new, probably adversarial, peers.
