Bundle build with tweak version fails

[ygorelik]

Expected Behavior

The bundle version should accept tweak number.

Current Behavior

When bundle version contains tweak, (ex.: 0.1.5-post1) the build fails due to cmake error or Python exception:

Example 1: version = 0.1.6-post1

CMake Error at CMakeLists.txt:3 (project):
  VERSION "0.1.6-post1" format invalid.

Example 2: version = 0.1.6.1

Traceback (most recent call last):
  File "./generate.py", line 468, in <module>
    output_directory = (generator.generate(options.bundle))
  File "/home/ygorelik/ydk-0.7.3/ydk-gen/ydkgen/__init__.py", line 89, in generate
    return self._generate_bundle(description_file)
  File "/home/ygorelik/ydk-0.7.3/ydk-gen/ydkgen/__init__.py", line 110, in _generate_bundle
    curr_bundle, all_bundles = resolver.resolve(tmp_file)
  File "/home/ygorelik/ydk-0.7.3/ydk-gen/ydkgen/resolver/bundle_resolver.py", line 297, in resolve
    root = Bundle(bundle_file, self.cached_models_dir, self.iskeyword)
  File "/home/ygorelik/ydk-0.7.3/ydk-gen/ydkgen/resolver/bundle_resolver.py", line 227, in __init__
    super(Bundle, self).__init__(data['bundle'])
  File "/home/ygorelik/ydk-0.7.3/ydk-gen/ydkgen/resolver/bundle_resolver.py", line 83, in __init__
    self._version = Version(*tuple(data['version'].split('.')))
TypeError: __new__() takes exactly 4 arguments (5 given)

Steps to Reproduce

In the bundle profile set version to have a tweak value.
