[PATCH blktests 07/14] check: Introduce group_exit() function

[Damien Le Moal]

From: Shin'ichiro Kawasaki <shinichiro.kawas...@wdc.com>

This optional function can be defined by a test group rc script. When
defined, it is executed after all tests of the group complete, allowing
cleaning up resources used by all tests of the group.
