🏁 automate cookiecutter release pipeline

We need to automate the release process of cookiecutter, so anyone that can createa tag/release on github repository will trigger a build that publishes the package on pypa.org. This is key in order to allow the project to move forward with lower maintenance efforths and not to lag behind.

In order to achieve this there are few tasks needed:

• create cookiecutter bot user on pypa and put the logo on gravatar
• add cookiecutter bot user to pypa as maintainer
• change cookiecutter email and credentials to be one where multiple maintainers have access (in case we need to reset credentials)
• add cookiecutter tokens on travis config
• update .travis.yml with release (deployment) code that runs on tag pushes (@ssbarnea)
• make the first pre-release or release using this process

Related to this is the proposal that I made to switch-to release-drafter and rely on github release pages instead of maintaining an in-repo file. Still, that proposal is not blocker for automating the process.

Funny story I got a reply from Travis about this 3 month after sending the support request, and that was not a confirmation that they fixed the issue (ugprade security key). Ditching Travis would be a big win for us.

Hi @ssbarnea I am not owner on pip, so cannot add somebody. But can trigger release. You know my skype (a.shpak)
