Description

Travis-CI config contains a number of configuration options still related to trusty, while the builds are done with xenial:

    - r-source
    - sourceline: 'deb http://cran.rstudio.com/bin/linux/ubuntu trusty/'
      key_url: 'keyserver.ubuntu.com/pks/lookup?op=get&search=0x51716619E084DAB9'
    - r-packages-trusty
    - mysql-5.7-trusty

It makes sense to cleanup that stuff, as jobs are failing, like here: https://travis-ci.org/github/alexott/zeppelin/jobs/695705591
