Use guanlecoja-ui contextual actions for forceschedulers

- remove previous unwired contextual actions (promote/rebuild)
- remove useless rawdata in build page

partially solve #2995:
Get rid of all the broken / unwired elements from the web UI.
The problem would be valid for all nested states, even if forcesched dialog is the only use case I can see now.

This is an important usecase for me to be able to integrate forcebuilds with other web applications. 

E.g from a bug tracker, you want to check a bunch of bugs that are in implemented states, click a button, go directly to the buildbot forcesched form, select a bunch of additional tests (via a forcesched parameter plugin, which queries the test plan REST api), and create an android build with the patches associated to the bugs + run the tests.
