[Enhancement]: Support filtering by tags for aws_ec2_transit_gateway Data source

[AliAllomani]

Description

Adding the support to filter transit gateways by tags for aws_ec2_transit_gateway Data source would be beneficial for use-cases where filtering by the available options supported by AWS API is not sufficient

Filtering by tags can be performed on terraform provider level

Affected Resource(s) and/or Data Source(s)

• data.aws_ec2_transit_gateway

Potential Terraform Configuration

data "aws_ec2_transit_gateway" "example" {
  tags {
     Name = "tgw"
     Project = "MyProject"
  }
}

I've not tried this yet but would specifying the tag in the filter argument suffice as a workaround?

Like so:

data "aws_ec2_transit_gateway" "tgw" {
  filter {
    name   = "tag:Name"
    values = ["tgw-prod"]
  }
}

Or

data "aws_ec2_transit_gateway" "tgw" {
  filter {
    name   = "tag:costcode"
    values = ["1234","4321"]
  }
}

data "aws_ec2_transit_gateway" "tgw" { filter { name = "tag:Name" values = ["tgw-prod"] } }

Thanks @djsd123 , I have tested it and that works fine !

interestingly the usage of tag: as a filter name is not mentioned in AWS docs for DescribeTransitGateways

• https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeTransitGateways.html
• https://docs.aws.amazon.com/cli/latest/reference/ec2/describe-transit-gateways.html

aws ec2 describe-transit-gateways --filters "Name=tag:Name,Values=tgw-prod"

With that, I'm closing this issue as the current filters argument is sufficient for such use-case
