Major Description
We've added a new monitoring endpoint to improve the resource usage naming scheme, and remove cpu_usage (which was a source of confusion as it's based on an arbitrary 5 second interval).
Old: http://localhost:5051/monitor/usage.json (deprecated in 0.13.0)
New: http://localhost:5051/monitor/statistics.json (added in 0.13.0)
The old endpoint contained the following per-executor:
'cpu_time'
'cpu_usage'
'memory_rss'
The new endpoint contains the following per-executor:
'cpus_user_time_secs'
'cpus_system_time_secs'
'cpus_limit'
'memory_rss_bytes'
'memory_limit_bytes'
In 0.14.0 we will remove the old endpoint.
