Adds bfd and md5 auth support to google_compute_router_peer

(Check if supported/required in modules first!)

  • modules/ncc-spoke-ra (BFD + MD5 Auth are unsupported)
  • modules/net-ipsec-over-interconnect (Done)
  • modules/net-vlan-attachment (Done)
  • modules/net-vpn-dynamic (MD5 Auth unsupported, BFD unclear)
  • modules/net-vpn-ha (Done)
  • blueprints/networking/ha-vpn-over-interconnect (IMHO overkill)
  • fast/stages/2-networking* (specifically for **/vpn-onprem.tf) (IMHO overkill)

Quoting BFD docs:
You can only enable BFD in BGP sessions that you configure for VLAN attachments in Dedicated Interconnect or Partner Interconnect. BFD is not supported in BGP sessions that are configured for HA VPN tunnels or for Router appliance, which is part of Network Connectivity Center.

Quoting HA-VPN over Cloud Interconnect docs:
Enabling Bidirectional Forwarding Detection (BFD) does not provide faster failure detection for HA VPN over Cloud Interconnect deployments.

MD5 auth docs:

Products that can use MD5 authentication include the following:

- [HA VPN](https://cloud.google.com/network-connectivity/docs/vpn/concepts/overview#ha-vpn)
- [Cloud Interconnect](https://cloud.google.com/network-connectivity/docs/interconnect/concepts/overview)
