Add glProjectName to logs

This enables the Gitaly logs to have the full human-readable GitLab project path, which is helpful to have for log aggregators when hashed storage is in use.

glRepository provides an identifier in the form of project-<id>, but this field is blank when a project is created.

Bump to gitaly-proto v1.10.0 and add required stubs.
