oci_kms_key error "no such host" during terraform apply on OCI: just wait a few minutes and retry!

Hi, first time installing Cloudblock using OCI Free tier. Thanks for putting this detailed project out, it is very instructive =)

During terraform apply -var-file="oci.tfvars" I got stumped by the following error:

[...]

When I clicked on the URL, my browser opened to the following content:

{
  "code" : "NotAuthenticated",
  "message" : "The required information to complete authentication was not provided or was incorrect."
}

I tried to relaunch the same terraform apply -var-file="oci.tfvars" command, but obtained the same errors.

At first I thought it was because I was using the Cloud Shell which was not part of your instructions (but is a great way to skip installing terraform/oci-cli/ansible btw), so I terraform destroy from the Cloud Shell and then tried it from my local machine.

However it failed with a similar error, although only one this time:

╷
│ Error: Post "https://h5sxwky2aaa3c-management.kms.eu-paris-1.oci.oraclecloud.com/20180608/keys": dial tcp: lookup h5sxwky2aaa3c-management.kms.eu-paris-1.oci.oraclecloud.com on 1.1.1.1:53: no such host

╵

So I started writing up an issue on GH, a few minutes passed and right before submitting the issue I tried to relaunch the terraform apply command. And this time it worked!

So for anyone having the same issue: just wait a few minutes for the kms/vault thingy to be initialized, and then retry with the same command!

Hope it will come in handy for some.
Cheers!
