2.6.0: Drop of Centos7 support

This release comes after almost 2 years since previous one.
I've not been very active on this project.
I recently found the time to update all build dependencies (Conan, Prometheus-cpp, docker tags, Github actions, etc) and get this new fresh release out.
To be able to build & compile the RPMs for newer platforms though I've taken the decision to drop Centos7/EPEL7 support (they lack a GCC compiler with c++14 support!). So if you're using the tool on that OS, please stick with the previous version.
