Reporting: prettier phased test report with 2D table

Currently, the test report for phased tests is presented as a list.
What we want is to improve the readability of the phased test report in
order to further highlight potential problems in the product we test.

Expected Behavior

Ideally we would have something like this:

Phased group | Steps before phased event | Steps after phased event
-- | -- | --
n, m | n number of test steps | m number of test steps)
3, 1 | step_1, step_2, step_3 | step_4
2, 2 | step_1, step_2 | step_3, step_4

...

, where n, m represent some possible phase group.

The steps that have failed would had been accentuated by a red color, for example.

Actual Behavior

This is what we have today:

phased-shuffledGroup_n_m_stepX

phased-shuffledGroup_3_1_step_1

phased-shuffledGroup_3_1_step_2

phased-shuffledGroup_3_1_step_3

Phased Event

phased-shuffledGroup_3_1_step_4

phased-shuffledGroup_2_2_step_1

phased-shuffledGroup_2_2_step_2

Phased Event

phased-shuffledGroup_2_2_step_3

phased-shuffledGroup_2_2_step_4

...

presented in rows, one after the other.
