Description

Adds a new resource aws_ec2_local_gateway_route_table_virtual_interface_group_association that manages the association between an EC2 Local Gateway Route Table and a Virtual Interface Group on AWS Outposts.

This is a straightforward CRUD resource (Create/Read/Delete, no Update) that wraps the CreateLocalGatewayRouteTableVirtualInterfaceGroupAssociation, DescribeLocalGatewayRouteTableVirtualInterfaceGroupAssociations, and DeleteLocalGatewayRouteTableVirtualInterfaceGroupAssociation EC2 APIs. Both required arguments (local_gateway_route_table_id and local_gateway_virtual_interface_group_id) are ForceNew since the API does not support modifying an existing association. Tags are the only in-place updatable attribute.

Implementation uses terraform-plugin-framework + aws-sdk-go-v2. Async state transitions (associating → associated, disassociating → removed) are handled via waiters with a 5-minute timeout.

Relations

Closes #48006.

Output from Acceptance Testing

Tests require an AWS account with Outpost hardware. Tests are gated by acctest.PreCheckOutpostsOutposts and will skip in environments without Outposts.

Acceptance test output to be added once run against an Outpost-enabled account.
