Helper determines if the code is running in CI environment by checking
the INTEL_CI environment variable. It can be useful for reducing number
of dynamic subtests executed in CI runs. While some subtests should be
defined, because they can be valuable for debugging or platform bring
up, running all of them in CI for every build is not always necessary.

For example, in the case of SR-IOV tests, while the ability to run test
on a specific VF is important, executing it on all possible VFs in CI
for every build might not be required. In many cases, testing on a single
random VF is sufficient and testing on every possible VF would
significantly increase execution time and CI infrastructure load.
