Add Historic CPU and memory stats (#7136)

Browse Source 
Collect historic cpu and mem stats.  Also, use actual values 
instead of formatted strings while returning to the client. The string 
formatting prevents values from being processed by the server or 
by the client without parsing it. 

This change will allow the values to be processed (eg. 
compute rolling-average over the lifetime of the minio server)
and offloads the formatting to the client.
