Also reduced the number of environment variables which simplifies
the documentation and requirements. The variable names now match
those used by the OCI CLI.

This plugin is has noticeably more required fields than most
other plugins due to the requirement that all requests to
the OCI REST API must be cryptographically signed by the client
using the draft standard proposed in draft-cavage-http-signatures-08[1].
The OCI specific implementation details of the draft standard are
documented in the Developer Guide[2].
NOTE: there is maximum allowed clock skew of five minutes between the
client and the API endpoint. Requests will be denied if the skew is
greater.
This PR also includes a minor tweak to the Solaris job in the DNS
workflow so that it uses the pre-installed GNU tools, curl and OpenSSL 1.1.1.
Without these changes, the signature generation function does not
work on Solaris.
