* update layout for pipelines

* add edit icon

* rename deployment actions

* add panels for pipelines tab

* change deployment stats layout

* remove redundant fields from node details

* render roles with badges

* format nodes attrs

* hide empty stats tab

* enable trained models tests

* add canViewMlNodes capability, hide Nodes tab for the viewer

* remove unused translation

* support force stop

* import default ml capabilities in the security_solutions plugin

* update translation string id

* Revert "support force stop"

This reverts commit 1b1a3b2
