[Promise test case] Use proper way to get parameters from yaml

Since there is a function in functest_utils to get
a value from the config_functest.yaml directly, there
is no need to load again that file. Better to use common
functions that are designed for that.

Also, Replace location of the results json file to
the results directory. It will be also pushed to artifacts
repository.
