automate deployment of packages to bintray

[weakcamel]

Plan of action:

• set up repositories for DEB and RPM packages
• automate DEB and RPM packaging using existing recommended method (setuptools bdist_rpm / bdist_deb)
• set up access token for Bintray
• add another deployment provider (on top of PIP) to Travis YAML file to publish releases:
  • ideally differentiate between stable and unstable releases

Note: credentials need to be secured.

Supplementing material:

• https://bintray.com/docs/usermanual/formats/formats_yumrepositories.html
• https://docs.travis-ci.com/user/deployment/bintray/#Descriptor-file-example
• https://docs.travis-ci.com/user/multi-os/
• https://docs.travis-ci.com/user/installing-dependencies/

As it turned out, deployment with Bintray Travis publisher is completely unreliable. Travis happily fails and reports success of a failed deployment.

Also the matrix parameters don't get properly handled so deployment of DEB packages fails. So bad...

Switching to a provider: script and a deploy script instead
