[skip ci]

Make sure alert notifier provisioning directory are created for deb and rpm packages

Fix navigate to folder with only uid

-f check if a file exists. -d checks if the dir exists

Fix for logs graph series names (level names)

as noted, sessions might not be a good name for this metrics.
while devices would be a better name for users I think we should
align the name with the code as much as possible. The ui listing
all auth_tokens per user should probarbly say "devices" instead

adds usage stats for sessions
