Add support for External VPCs in SDDC Group

[lscheidler]

Is your feature request related to a problem? Please describe.

I want to automate the AWS Account Association and attachment of External VPCs in the SDDC Group resource.

Describe the solution you'd like

resource "vmc_sddc_group" "sddc_group" {
   name  = var.sddc_group_name
   description    = var.sddc_group_description
   sddc_member_ids = [vmc_sddc.sddc_1.id, vmc_sddc.sddc_2.id]

  vpc_attachments {
    account_id = "012345678901"
    vpc_id = "vpc-12345678901234567"
   configured_prefixes = "10.0.0.0/8"
  }
}

Not sure, how we can handle external dependencies here (External AWS Accounts needs to accept request), so maybe it more like a shot and forget scenario here. Or maybe it makes sense to separate it to an additional resource.

Describe alternatives you've considered

There is no alternative despite using the web UI (which is in my opinion not a real alternative)

Additional context

Hi @lscheidler
Are those external VPCs deployed on VMC or they are completely external resources, deployed outside VMC ?

Hi @vasilsatanasov,

this AWS Accounts are external resources. So the idea behind it, is to automate the workflow of:

• Add external AWS Account ID to "External VPC"
  
• Accept the VPC
• Create prefixes for that VPC on VMC site

Hi @lscheidler since there is an UI for it there should be possibility to automate this. I will dig deeper and will follow up on this when I have more info.
