Adjusted for pypi support

We need to adjust the python module structure meet the pypi
requirements. This has been tested on test pypi
https://test.pypi.org/project/vnfsdk.

1. move 3 directories cli/ validator/ packager/ into vnfsdk_pkgtools. so
now the python module for vnfsdk pkgtools would be "vnfsdk_pkgtool.*"

2. Added missing README.rst, LICENSE.txt according to pypi requirement.

3. Added new version mechanism accroding onap community suggestions.

4. Other clean sweep job like dos2unix.
