infra: update configuration for the different environments

[slint]

We currently have a bit of a mix/conflict between configuration sources:

• this repo's invenio.cfg
• GitLab repository with OpenShift Helm charts values: https://gitlab.cern.ch/zenodo/zenodo-rdm-openshift/
• What is actually the deployed/live config on the various OpenShift projects (ConfigMaps and Secrets)

Given that multiple new features require specialized secrets/config (#500, #522, OpenAIRE direct indexing), we should take the chance to reconcile all these config sources.

Some important notes:

• Application config (available even in local development) should be only in invenio.cfg (or even in upstream modules if it makes sense IvnenioRDM-wide). One such example is the GITHUB_WEBHOOK_RECEIVER_ID = 'gtihub' (we would never use a different value in dev/prod/QA).
• Ideally, we should always aim at using helm upgrade (or similar) to apply any configuration changes to the deployed environments
• Synchronize with @psaiz as well for changes to the GitLab repo, since there is some ongoing parallel work on OpenShift infra at the moment

Moved or removed configs from OpenShift

I've found that the following configs could be removed from openshift:

• GITHUB_WEBHOOK_RECEIVER_ID (removed from zenodo-rdm-openshift, it's added by the module and should work)
• GITHUB_INTEGRATION_ENABLED (removed from zenodo-rdm-openshift, already exists in zenodo_rdm/invenio.cfg)
• DATACITE_ENABLED (removed from zenodo-rdm-openshift, already exists in zenodo_rdm/invenio.cfg)
• DATACITE_PREFIX (removed from zenodo-rdm-openshift, already exists in zenodo_rdm/invenio.cfg)
• GITHUB_RELEASE_CLASS (removed from openshift, already in invenio.cfg and added a default in invenio-app-rdm)
• MAIL_DEFAULT_SENDER (removed from openshift, moved to invenio.cfg)

Added configs

• OPENAIRE_API_CREDENTIALS
• logstash configs
