Display full branch name in commit column
Description
Note from customer: We are having problems seeing the name of the branches in the pipelines and environments, they are truncated and there are very few characters visible. This makes quite cumbersome to know which branch to select for deployments.
Proposal
Per https://gitlab.com/gitlab-org/gitlab-ce/issues/36917#note_38804875 we will display a tooltip containing the full branch name when hovering over the abbreviated branch name.
