💪🏾 Split components into dedicated packages

[candoumbe]

Describe the work that need to be done

In order to solve #70, a new set of packages must be added as dependencies to the current Candoumbe.Pipelines. As of now, any project depending on that package also take dependency on packages that will never be used.

Reorganizing code and split'ting components into specific / dedicated packages could help mitigate this issue :

• Candoumbe.Pipelines.Core.Components : reusable components for all pipelines / builds
• Candoumbe.Pipelines.Github : packages for everything that is related to Github
• Candoumbe.Pipelines.Docker : packages for everything that is related to Docker
• ....

All packages should follow the same version number and only depends on the "core" components + dependencies that are specific to their area of expertise
