This commit segregates interface that is require to make CI/CD entity
processable, like `Ci::Build`. With this change it is not clear and
explicit what methods need to be implement to pass an object to pipeline
processing service.

Fix vertical alignment of search box icons in issue board switcher for Safari

Closes #9240

See merge request gitlab-org/gitlab-ee!9190

Create the sandbox group with appropriate permissions before the LDAP
group sync test starts so that in subsequent tests the LDAP user has
permission to the group.

This also restores the original (most likely nil) env personal access
token, so that subsequent tests don't perform API calls as the root
user while logged in and performing other actions as a non-root LDAP
user.

Without this change groups would be created by the root user, so when
the LDAP user tried to push, it would not be permitted.

Remove unwanted margin above suggested changes.
