Add Gitaly data to the usage ping

Gitaly data wasn't available to the team, an this change is a first
iteration towards understanding what data we need and how to interpret
it. Later more values will be added.

For now the most important thing is the filesystem String Array, as that
includes data on ext4 exposure and NFS.
