[RFE] Use Travis-CI for beakerlib repository on github

[mnalband]

Description:

Every time, when we add some commits/PR, etc to the repo, there is no any run with sanity checks (e.g.unit-tests). We can add, for example Travis-CI feature to solve that problem.

Steps:

1. Authenticate with OAuth on https://travis-ci.org/ (should do the maintainer of the repository).
2. Flick the repository switch on here:
   https://travis-ci.org/profile/$USERNAME
3. Add to root file .travis.yml such as:

language: bash

sudo: false

install:
    - pip install -U pip
    - pip install --user -U rpm

before_script: cd src/test

script:
- bash test.sh 

4. Somehow skip tests, that are expected to fail. From beakerlib/src/test/README

Some of the tests are expected to fail (backup functions
need root permission and the coverage test suite fails because...
well because the coverage is not complete... yet :-)

I didn't add them because I faced with another problem (specific for beakerlib project): check out build log here:
https://travis-ci.org/mnalband/beakerlib/builds/346725708
