Distribute DE as whl with proper dependencies and install other system dependencies as RPM

[vitodb]

This PR adds the spec file with RPM dependencies for DE and the setup to build DE whl.

Some notes:

• This spec file is derived from the spec file we got from setup.py
• To properly set the RPM version the rpmbuild command needs to be executed from inside the decisionengine repo folder.
• Among dependencies we have build tools, those are needed because the jsonnet python module needs to be built from source.
• podman is needed to run redis server 6 container.
• The %description section could need to be reviewed, it has couple of lines commented out that probably were intended to be section header.
• To install the RPM obtained from this spec file, it is needed to enable CRB repo, as there are dependencies from that repo.
• following folders owned by decisionengine are created:
  /etc/decisionengine/
/var/log/decisionengine/
/var/lib/decisionengine/
  and configuration file /etc/decisionengine/decision_engine.jsonnet is included
• Jenkins pipeline and GH actions have been updated to build DE whl and RPM with DE dependencies
• Jenkins pipeline and GH action that build RPM from setup.py have been removed

Dependencies not included:

• postgresql postgresql-server:
  Currently we have a version of postgresql RPM from EL9 repo compatible with DE, with EL7 we needed to pick a postgresql version from official postgresql repositories.
• htgettoken:
  We need this to create scitokens. This is need for integration tests, but is not a real DE requirement.

Other improvement that could be added are:

• set decisionengine as owner of /var/lib/gwms-frontend
