* [JENKINS-22474] API Token does not require CSRF token
- in order to ease the use of the api, we are not requiring the request to have a crumb
- in terms of security it's not a problem normally since the CSRF attacks use the cookies and in case of API Token, it's session-less / cookie-less
* - adjust the license header
* - add test for basic authentication
- add test for login process
* - add test for form submission using ui (htmlunit), not just login form
* - modification requested by Jesse
* - pom.xml update to use the last version of jenkins-test-harness (with the token helper methods)
- beginning of the simplification of tests
* - using the try-with-resource approach to ease readability
* - using closure method now
* - add missing login transformation
* - add unit test
* - use withToken
- remove useless crumb for GET method
- add fail (otherwise the assert in catch is not as useful as it could be)
* another bunch of test cases
* - for HudsonTestCase, some additional modifications are required: changing the view / different type of management for the variable inside the views
* - small other tests
* - last batch for the login method
* - crumb is not more required since we are using API Token
* - converting auth to ApiToken to avoid crumb method
* - converting auth to ApiToken to avoid crumb method (second)
* - remove usage of closure aware methods
* - update the pom using the snapshot as adviced by Jesse
- modifications on other class to adapt to the last modifications in JTH
* - modifications requested during code review
* - also put back my changes to the conflicted file
* - correction of the merge :)

Also reduce the time 250 ms (instead of 1 second previously) between
retries to hopefully reduce the test duration on quick enough setups,
and still degrade nicely on less performing ones.
