Add OCP Engine with filter for OLS tarballx

[epapbak]

Description

• Add OCPEngine , which is basically the ICM engine with a filter for when openshift_lightspeed.json file is found in ht tarball's root directory.
• Add corresponding unit tests
• Add ols label value in StatsWatcher, so that metrics are updated with the ols archive type when possible

Cons of this approach: Our OCP engine used to use be the ICM engine, used directly. We now lose the updates made there if the process method is ever updated. But this is supposed to be temporary, so let's not delve on that.

Fixes CCXDEV-12725 partially (config update needed in ccx-data-pipeline)

Type of change

• New feature (non-breaking change which adds functionality)

Testing steps

Updated UTs

Checklist

• pre-commit run -a passes
• updated documentation wherever necessary
• added or modified tests if necessary
• updated schemas and validators in insights-data-schemas in case of input/output change

The OLS team announced today that they will be starting to send their archives with a different User-Agent.

If it is possible, probably we can filter them out because the service header, so please wait until tomorrow before merging and using this engine.

I'm not 100% sure tomorrow they'll have a different service header that we will be able to use, but it makes sense to wait and see indeed.
