LXC description field is always marked as changed

[simoncaron]

Describe the bug

When the description field of an LXC container is written using heredoc syntax, ex:

  description = <<-EOT
    my 
    description
    value
  EOT

the provider will always find a change in the resource at each run.

To Reproduce
Steps to reproduce the behavior:

1. Create an LXC resource with a multi-line heredoc-style description
2. Run terraform plan/apply immediately after creation
3. Check output of the command

Expected behavior
Since the description field was not changed, there should not be any change detected.
