test/py: Add a report show test durations
Execution time varies widely with the existing tests. Provides a way to
produce a summary of the time taken for each test, along with a
histogram.
This is enabled with the --timing flag.
Enable it for sandbox in CI.
Example:
Duration : Number of tests
======== : ========================================
<1ms : 1
<8ms : 1
<20ms : # 20
<30ms : ######## 127
<50ms : ######################################## 582
<75ms : ####### 102
<100ms : ## 39
<200ms : ##### 86
<300ms : # 29
<500ms : ## 42
<750ms : # 16
<1.0s : # 15
<2.0s : # 23
<3.0s : 13
<5.0s : 9
<7.5s : 1
