When optional provider.docker.cert_path is empty, plan/apply always prompt

[jefferai]

Not having the value set (which is the general/popular case; it is rare to set TLS configuration information unless you're going across hosts) results in the following prompt every time terraform plan or terraform apply is run:

$ terraform plan
provider.docker.cert_path
  Path to directory with Docker TLS config

  Enter a value:

Pressing enter (leaving the value blank) allows Terraform to get on with it.

This is probably not an error specific to the Docker provider; @phinze suggested that this might be the first time there is a provider configuration value that is optional, so it's just exposing an existing bug. Regardless, it's marked as optional in the provider code, so it should not be prompting for it.
