Feature Request - Statically Allocate BGP peering IPs (similar to #562)

[fengwang523]

This request is similar to #562

For border leaf BGP peering sessions with generic system, the same challenge applies.

The BGP peering IPs are allocated by a role "to_generic_link_ips" to an IP pool mapping. Here is an example code:

resource "apstra_datacenter_resource_pool_allocation" "tf_rz_ipv4_external_allocation" {
count = var.rz_ipv4_external_pool != null ? 1 : 0
blueprint_id = var.bp_id
role = "to_generic_link_ips"
pool_ids = [apstra_ipv4_pool.tf_rz_ipv4_external_pool[0].id]
routing_zone_id = apstra_datacenter_routing_zone.tf_rz.id
}

The peering IPs are dynamically allocated, therefore the values are not known until terraform apply and they would change upon destroy and re-apply.

The feature request is that to be able to hardcode the peering IPs using values from the IP pool.
