[PATCH] lib: framework: Increase precision of progress, add a spinner progress indicator

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Some tests such as the cpufreq and cstates tests take rather a long time so it
makes sense to increase the precision to the % progress output to indicate that
something is actually happening.  Also, add a progress spinner indicator to also
provide some feedback that the test is actually active rather than hung.
