Checklist

[x] Is your issue/contribution related with enabling some setting/option exposed by libvirt that the plugin does not yet support, or requires changing/extending the provider terraform schema?
- [x] Make sure you explain why this option is important to you, why it should be important to everyone. Describe your use-case with detail and provide examples where possible.
- [x] If it is a very special case, consider using the XSLT support in the provider to tweak the definition instead of opening an issue
- [x] Maintainers do not have expertise in every libvirt setting, so please, describe the feature and how it is used. Link to the appropriate documentation
[x] Is it a bug or something that does not work as expected? Please make sure you fill the version information below:

Description of Issue/Question

I'm trying to us this provider with a sshkey provided via a separate Terraform resource. The provider seems to init too fast and doesn't let the uri value render first.

Setup

This was my final attempt to make the provider work via inducing a dependency for the URI to a data read

terraform {
  required_providers {
    libvirt = {
      source  = "dmacvicar/libvirt"
      version = "~> 0.7"
    }
  }
}

provider "libvirt" {
  uri = "qemu+ssh://root@libvirt:2222/system?no_verify=1&keyfile=${data.external.id_rsa.result.path}"
}

data "external" "id_rsa" {
  program = ["echo", <<EOT
{"path": "./id_rsa"}
EOT
  ]

  depends_on = [
    local_sensitive_file.id_rsa
  ]
}

resource "local_sensitive_file" "id_rsa" {
  content = ${some_other_resource.key}
}

Steps to Reproduce Issue

Additional information:

Do you have SELinux or Apparmor/Firewall enabled? Some special configuration? Have you tried to reproduce the issue without them enabled?
