Create new metapackage to abstract out oracle instantclient
Problem
CTA depends on the CERN oracle-instantclient
RPM, but we don't have permission to distribute this outside CERN.
Oracle distributes public RPMs but the version we are using is not guaranteed to be available.
This has to be resolved for the public release.
Proposal
Can we create a meta package which can depend on CERN Oracle instantclient RPM or public Oracle instantclient RPMs? Basically something that satisfies the Oracle symbols for external users (who are mostly using Postgres).
Note
External sites (apart from RAL) are in any case not using Oracle and in principle should not have to install Oracle libraries. But disentangling Oracle lib dependencies from our code is not a trivial task.
