To prevent parameters having to be converted individually for each worload
the getParams() function has been overridden to perform the required type and
url decoding on the passed parameter bundle before passing the correctly typed
bundle to the workloads.
Log time changed to produce epoch time in milli seconds.
Nano to milli second conversion done in uxperf result
processor is removed.
Tested on Mate8 and time obtained is verified.
