- template generation (it would break on first error when getting a milestone URL - now we're falling back to fixed values)
- updated tests to not work against Greenwich (lol) but a more recent branch
- fixed Sagan updater to use the new docs link
The rationale of this pull request is to
* have more maintainable and granular code
* not maintain the custom made job engine
* allow the users to customize the defaults of the releaser more easy
* allow the users to create their own steps without the need to change any existing code
* allow the users to fully change the flows and tasks logic
* abstract underlying batch mechanism (Spring Batch) so it doesn't leak to production code
* allow parallelization of the release process and release tasks
