feat: use shared workflows from .github repository

[gatici]

Use shared workflows from https://github.com/omec-project/.github repository.
This PR uses existing workflows from a common repositories named .github which stores all the shared workflow templates.

Note: omec-project/.github#1 should be merged first.
Please disregard the previous conversions about E2E tests. This PR only adds the existing workflows.

Please check whether the issue with the CRDs (e2e GHA) is due to the registries I removed in this commit: gab-arrobo/aether-in-a-box@22a1595

Shouldn't this use the shared workflow files? For testing, I think we can target the branch directly.

@gatici @ghislainbourgeois, I think we can avoid using the DockerHub credentials by using a local registry with the help of this GitHub Action (https://docs.docker.com/build/ci/github-actions/local-registry/). What do you think? The only thing is that I am pretty certain current Helm Charts do not support different registry per NF's image. That is, all images should come from the same registry. However, this is something we can properly address in the Sdcore Hel Charts

Hello @gab-arrobo ,
I updated E2E tests section to use charmed-kubernetes using relevant Github action. Helm chart is deployed successfully. At the moment, UPF pod stuck in init status. Other pods become active.
I guess the following line is the reason of the problem.
https://github.com/omec-project/sdcore-helm-charts/blob/4bf08f220245f3d8384126a96b5c2ccec4f8003b/bess-upf/templates/statefulset-upf.yaml#L101
5:03
Where is the PCIDEVICE_INTEL_COM_INTEL_SRIOV_DPDK variable defined ? Could you please help on this ?
I sent you the UPF pod details through Slack.
Many thanks!

@gatici,
From the e2e-test log, there is an error loading the sdcore-5g-values.yaml because of this Condition path '5g-ran-sim.enable' for chart 5g-ran-sim returned non-bool value, the value should be either true or false, but since the file is not properly passed, the variable enable: ${ENABLE_GNBSIM} (https://github.com/gab-arrobo/aether-in-a-box/blob/master/sd-core-5g-values.yaml#L361) is not getting overwritten. Therefore, it looks like the other values are not being overwritten, either. So, the default deployment mode for the UPF is DPDK and that might be the reason why your UPF pod get stuck in initialization state.

Hello Gabriel,
ENABLE_GNBSIM is set to true while we are running helm command. It should not create a problem.
This error happened once ( strange) but it does not appear again.
gnbsim and UPF pod does not become available.
And I am suspicious about Multus.
