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.

+ONAP VNFSDK CSAR Package Tool
+========================
+VNFSDK package tool provides VNF product DevOps engineers with the tools to manage the VNF package content. The tools are provided in a form of a shared library (Python module) that can be used in other projects. A CLI is also provided out-of-the box for DevOps to use the library with their scripts and automation framework.
+
+Source Code: https://git.onap.org/vnfsdk/pkgtools
+
+Usage
+-----
+- Create CSAR package
+      $ vnfsdk csar-create -d DESTINATION [–manifest MANIFEST] [–history HISTORY] [–tests TESTS] [–licenses LICENSES] source entry
+- Extract CSAR package
+      $ vnfsdk csar-open -d DESTINATION source
+- Validate CSAR package
+      $ vnfsdk csar-validate source
+
+All commands have -h switch which displays help and description of all parameters.
