NSB PROX NFVi Test does not stop after reaching expected precision

JIRA: YARDSTICK-1419

When using prox_binsearch algorithm, a binary search is
performed, increasing lower bound when step was successful
and decreasing upper bound when the step was a failure.

This runs until the test_precision (as specified in the
traffic profile) is reached. When the test precision
is reached, the test is not completed until the
runner duration is reached.

As runner duration is usually high (e.g. 1800sec), the
tests take much too long to execute.
This makes it difficult to create test suites.
