Since python 2 will be end of life. In Frankfurt release, we need to migrate to python3.

A ansible-example-server directory exists in the ccsdk/sli/adaptors repository, which appears merely to be an unmaintained, less developed older copy also seen in csdk/distribution repository.

Rather than updating the adaptors copy, it should be removed in favor of maintaining the newer copy further. The ansible-example-server seems to be standalone and not referenced by anything else in the adaptors repository anyway.
