[Kimchi-devel] [PATCH V2] [Kimchi] Isolate unit tests execution.

[pvital at linux.vnet.ibm.com]

From: Paulo Vital <pvital at linux.vnet.ibm.com>

This patch isolates each unit test execution reducing the occurrences of tests
using data from previous unit tests and making results not reliable.

In addition, it also simplifies the output of tests execution, printing the tags
PASSED and FAILED and the error/failed banners only when necessary.
