WIP: Add catkin_lint feature.

An enhancement mentioned in ros-industrial#98

Some considerations:
- By default `catkin_lint` is run with `--strict` option, which makes the job fail even when there's only warning returned by catkin_lint. I'm not sure if we want to allow disabling --strict option on CI (those who just want the result without failing the CI job can run catkin_lint locally IMO).
- `catkin_lint` runs between build-install and tests, which I'm not sure is the best location.

 * `BUILD_PKGS_WHITELIST` (default: not set): Packages to be built can be explicitly specified with this, in ROS package name format (i.e. using underscore. No hyphen). This is useful when your repo contains some packages that you don't want to be used upon testing. Downstream packages, if necessary, should be also specified using this. Also these packages are to be built when `NOT_TEST_INSTALL` is set. Finally, packages specified with this will be built together with those speicified using unimplmented `USE_DEB`.
 * `BUILDER` (default: catkin): Currently only `catkin` is implemented (and with that `catkin_tools` is used instead of `catkin_make`. See `this discussion <https://github.com/ros-industrial/industrial_ci/issues/3>`_).
 * `CATKIN_CONFIG` (default: not set): `catkin config --install` is used by default and with this variable you can 1) pass additional config options, or 2) overwrite `--install` by `--no-install`. See more in `this section <https://github.com/ros-industrial/industrial_ci/blob/master/doc/index.rst#optional-customize-catkin-config>`_.
+* `CATKIN_LINT` (default: not set): If true, run `catkin_lint <http://fkie.github.io/catkin_lint/>`_ with `--strict` option, which means if there's any warning the job fails. It runs between build and install.
+* `CATKIN_LINT_ARGS` (default: not set): If true, you can pass whatever argument(s) `catkin_lint` takes, except `--strict` that is set by default. Delimit by space if passing multiple.
 * `CATKIN_PARALLEL_JOBS` (default: -p4): Maximum number of packages to be built in parallel that is passed to underlining build tool. As of Jan 2016, this is only enabled with `catkin_tools`. See for more detail about `number of build jobs <http://catkin-tools.readthedocs.org/en/latest/verbs/catkin_build.html#controlling-the-number-of-build-jobs>`_ and `documentation of catkin_tools <https://catkin-tools.readthedocs.org/en/latest/verbs/catkin_build.html#full-command-line-interface>`_ that this env variable is passed to internally in `catkin-tools`.
 * `CATKIN_PARALLEL_TEST_JOBS` (default: -p4): Maximum number of packages which could be examined in parallel during the test run. If not set it's filled by `ROS_PARALLEL_JOBS`.
 * `CCACHE_DIR` (default: not set): If set, `ccache <https://en.wikipedia.org/wiki/Ccache>`_ gets enabled for your build to speed up the subsequent builds in the same job if anything. See `detail. <https://github.com/ros-industrial/industrial_ci/blob/master/doc/index.rst#cache-build-artifacts-to-speed-up-the-subsequent-builds-if-any>`_
