Write Wiki pages for how-to and troubleshooting

[ozangunalp]

Proposed by @headcrabmeat in #50

Discussions in issues are ok but when the issue is closed it is not easily available to newcomers.

Write how-to pages resuming the solutions described in issues and troubleshooting for common issues and misunderstandings.

Hi @ozangunalp!

Thanks for this useful framework! Some how-to pages, specially starter projects would be useful.

I've build 2 examples, one with gradle and one with maven:

Gradle: https://github.com/nextlayer-ops/jenkins-pipeline-shared-library-example Maven: https://github.com/nextlayer-ops/jenkins-pipeline-shared-library-example-maven

Maybe you can use them ;)
