• add melodic test

In kinetic, travis failed because https://github.com/locusrobotics/catkin_virtualenv/pull/49 is not released to kinetic. I made a release request -> https://github.com/locusrobotics/catkin_virtualenv/pull/49#issuecomment-607247372

In indigo, I found the following error that I don't know. I'll do further investigation:

DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. A future version of pip will drop support for Python 2.7.

Or we can drop Indigo and add Melodic.

[knorth55]

I tried melodic docker build locally, but it fails because of this: https://github.com/jsk-ros-pkg/jsk_visualization/issues/764

[knorth55]

I disable melodic test now. I will reenable it later.

@pazeshun build passed in indigo without catkin_virtualenv
