Add a sync checker reporting each sync resource last "bytes" and "speed"

Example:

|- sync
|  |- sync#1.bytes                testmd  10292
|  |- sync#1.speed                testmd  211968.0
|  |- sync#2.bytes                testmd  0
|  |- sync#2.speed                testmd  0
|  |- sync#i0.bytes               testmd  605
|  |- sync#i0.speed               testmd  122.0
|  |- sync#i0.bytes               ha1     289
|  `- sync#i0.speed               ha1     57.0
