Draft first release of this script and little tool

[buep]

• readme updat
• roadmap
• contribution file
• add our git phlow to this repo
• create build automation and ci jobs
• release the script as version 1.0.0

[buep]

Waffle, github labels done.

[buep]

Release of the script will be done as an archive file to Github, including a release note.
Releases will equal tags, version will be part of the script output for traceability, but we will not as such version the script in our recommended way of distributing it. Breaking changes will be done as scanner vs scanner_v2 or similar.

The archive file should only contain docs, and scripts... not the rest of the repo.

Readme should include tips on distribution and use in Jenkins and other build systems. Especially a recommended way of distributing it, so it fits our release flow.

Could run the groovy test, only on my laptop, but no other systems (like our build slaves) and not even a new Ubuntu 16 build slave either.

Spent quite some time configuring a new slave and trying to look into the groovy execution problem.

[buep]

It was scope creep to try to fix the groovy problem, completing the release process but disabling running the tests.
