GitAction for code coverage

[fgalan]

The standard makefile generates a coverage report in coverage/ directory using a command like this:

make coverage INSTALL_DIR=~

It would be great to add this to GitActions, which means that also some modifications to the CI docker image has to be done. Some more detail about this task:

• I think that the following packages should be added to ci/rpm7/build-dep.sh: lcov and xsltproc
• A new stage for coverage (similar to functional test stage) has to be added to ci/rpm7/build.sh. The stage has to be included in the list in ci/README.md
• New targets for coverage should be added to ci/rpm7/makefile file (not sure... this file is quite a mistery to me and I don't know why don't the standard makefile at root level cannot be used in CI). Probably this is the hardest item.
• A new action (e.g. coverage.yml) has to be added in .github/workflows. When to run it? Every PR or only in master? I think only in master, as this is a long-time job and coverage is not critical for PRs.
• (Nice to have) Integrate with coveralls system so the coverage result is pushed to coverall when coverage.yml succesfully run. At the end we can even include a badget in the master README.md to show current coverage :)

@wistefan you have been recently involved wigh GitActions for Orion. It would be great if you could have a look and help with this, please :)

Hi, I wont have the time to do it myself in the next few weeks, but you can use the solution I built for orion-ld repo as starting point: Action with Coveralls integration: https://github.com/FIWARE/context.Orion-LD/blob/develop/.github/workflows/coverage.yml LCov in docker-image: https://github.com/FIWARE/context.Orion-LD/blob/develop/docker/Dockerfile-test#L5 Coverage for functional tests: https://github.com/FIWARE/context.Orion-LD/blob/develop/docker/build.sh#L337-L381 Coverage for unit-tests: https://github.com/FIWARE/context.Orion-LD/blob/develop/docker/build.sh#L293-L303 & https://github.com/FIWARE/context.Orion-LD/blob/develop/makefile#L348-L370
