Use Cases or Problem Statement

In the current implementation of this provider, it's possible to provide Private Key PEMs in PKCS#8 format to certificate resources and data sources. Yet, is not possible to use tls_private_key to get the key in PEM PKCS#8 format.

To be exact, we can get it only for tls_private_key created with algorithm = ED25519, as that's the only format Go crypto libraries support for it.

Proposal

Add a .private_key_pem_pkcs8 field to tls_private_key resource.
