No need to query data from TRSS when divide test lists on machine number

There are two ways to divide test lists divideOnMachineNum() and divideOnTestTime(). There is no need to query test time from TRSS for divideOnMachineNum().

Currently when call divideOnMachineNum() TRSS is queried and return no data, which doesn't help test division at all. For example, TCK run are using divideOnMachineNum() and each time TRSS is queried. Either TRSS is unavailable or no data at all, but always takes time and receive unnecessary and confused console output.

Locate divideOnMachineNum() and divideOnTestTime() in the TKG source and trace where the TRSS query is made. Confirm that machine-number division avoids the test-time lookup while time-based division retains it, then run the relevant test-list division or TCK workflow and verify the unnecessary console output is gone.
