logging: Drop topLevelGroup field
The topLevelGroup used to be important for logging as GitLab used to
store repositories in a directory structure mimicking the URL path. For
example gitlab-org/gitaly
used to be stored at
gitlab-org/gitaly.git
. Since 14.0 GitLab will no longer use the legacy
storage format this field will always read @hashed
.
If a field is always a constant, why log it? This change stops logging it.
Closes #3639 (closed)
