tools (common/template): add 2 new filters: `timestamp_to_hour` and `delta_to_human`:

`timestamp_to_hour` give the hour corresponding to a timestamp, it will be used to display
calendar for this time window.
`delta_to_human` convert a delta of 2 timestamp to human readable time using
`tools.common.date_utils` corresponding function.
