Add bypass_vlan_overlap_check parameter to cloudstack_private_gateway

[bhouse-nexthop]

• Add bypass_vlan_overlap_check optional parameter (defaults to false)
• Parameter allows bypassing VLAN overlap checks during gateway creation
• Update resource creation logic to pass parameter to CloudStack API
• Add comprehensive test coverage:
  • Test with bypass enabled
  • Test default value (false)
  • Update import test to ignore field (not returned by API)
• Update documentation with examples and parameter description
• All acceptance tests passing (4/4)

Pull request overview

Adds support for an optional bypassvlanoverlapcheck flag on cloudstack_private_gateway, enabling callers to bypass CloudStack’s VLAN overlap validation at creation time.

Changes:

• Documented the new bypassvlanoverlapcheck argument and added an HCL example.
• Extended the private gateway resource schema and create logic to pass the flag to the CloudStack API.
• Added/updated acceptance tests to cover explicit true, default false, and import behavior.

@bhouse-nexthop I found a bug.

1. apply the terraform

resource "cloudstack_private_gateway" "bar" {
  gateway = "10.1.1.254"
  ip_address = "192.168.0.2"
  netmask = "255.255.255.0"
  vlan = "2"
  vpc_id = cloudstack_vpc.bar.id
  acl_id = cloudstack_network_acl.bar.id
  bypass_vlan_overlap_check = true
  depends_on = ["cloudstack_vpc.bar","cloudstack_network_acl.bar"]
}

2. Change value of bypass_vlan_overlap_check = true to false and apply again.

  Enter a value: yes
