bgpd: Improve peer scaling

Reduce the amount of time it takes to bring up a large number of peers.

This is accomplished by removing jitter and reducing the number
of seconds to wait before connecting to a peer.

Edited-by: Paul Jakma <paul.jakma@hpe.com> for rebase conflicts, and to add
           jitter on connect timer back in. Can be removed in an update.
