## Problem
Periodic pagebench workflow runs periodically from latest main commit
and also allows to dispatch it manually for a given commit hash to
bi-sect regressions.
However in the dashboards we can not distinguish manual runs from
periodic runs which makes it harder to follow the trend.
## Summary of changes
Send an additional flag commit type to the benchmark runner instance to
distinguish the run type.
Note: this needs a follow-up PR on the receiving side.
