New widget CueLabelSlider both int and float slider (#1280)

* feat: New widget `CueLabelSlider` both int and float slider

* fix: remove feature from another branch

* Add `signals`, `getter` and `setter`

This will be used in branch `cuesubmit-jobs-from-config-file`, done here to avoid pulling the whole widget
