automatically create github branches, tags, release & a changelog whenever the version is bumped\released

[naorlivne]

Expected/Wanted Behavior

Similar to what's been done in https://github.com/naorlivne/parse_it Travis CI should be configured that whenever the version of the CLI is changed to do the following:

1. create a new tag of the matching version
2. create a new release of the matching version (should also create the tag)
   3, create a new branch of the matching version
3. use naorlivne/github-changelog-generator-dockerized docker container to auto create a changelog and push it to the repo

Actual Behavior

There are no release notes\changelog & all version branches & tags are manually created.

[naorlivne]

auto version tag & changelog added, creating branch & github release still needed to be added.
