Oracle Linux 7.3 images are no longer returned by oci_core_images

[briangustafson]

Many of the examples use Oracle Linux 7.3 images for instance resources, where this is specified by filtering on oci_core_images - see https://github.com/oracle/terraform-provider-oci/blob/master/docs/examples/load_balancer/lb_full/lb_full.tf#L126. The underlying ListImages API call has recently stopped returning Oracle Linux 7.3 (instead 7.4 is returned). That breaks these examples - a terraform plan will give an error about not having any results oci_core_images. To fix the examples, for now they will be changed to 7.4. However, this will be updated with a longer term fix in the near future.

Note that Oracle Linux 7.3 images are still available if you have the OCID, it's just not returned from ListImages. If you have a config that is failing because of this, you can find the image OCID used in the state file and use that directly instead of filtering on oci_core_images.

A temporary fix for the examples has been merged. I'll leave this issue open for a bit to give it visibility.

A long-term solution to this issue is being tracked with #352.
