Add GH Actions to build on PR and cron

[zmichaels11]

Adds in GH Actions CI to repository. Runs build and test for macOS-latest and ubuntu-18.04 on PR, push to master, and hourly cron.

Action ran in personal fork: https://github.com/zmichaels11/rosbag2_bag_v2/pull/1 I think the macOS build failed due to upstream Catalina issues

These actions will run here once merged in.

That's pretty awesome.

The action for ubuntu came back successfully, however when looking at the console output, the build seems to return non-successfully. Also, the actual package didn't build due to a lack of ROS1.

-- Override CMake install command with custom implementation using symlinks instead of copying resources
-- Found PkgConfig: /usr/bin/pkg-config (found version "0.29.1") 
-- Checking for module 'roscpp'
--   No package 'roscpp' found
CMake Warning at CMakeLists.txt:30 (message):
  Failed to find ROS 1 roscpp, skipping...

-- Configuring done

-- Build files have been written to: /home/runner/work/rosbag2_bag_v2/rosbag2_bag_v2/ros2_ws/build/rosbag2_bag_v2_plugins

Can we validate the actual return value of colcon to see whether errors/warnings occured during the build?

How do you think this package can run on OSX? Is there a way to install ROS1 within the same action?

This is using https://github.com/ros-tooling/action-ros2-ci I'll open up an issue over there, I think it just doesn't support ros1bridge properly.

Opened issue on https://github.com/ros-tooling/setup-ros2.

Required fixes for this PR:

• [x] Issue https://github.com/ros-tooling/setup-ros2/issues/21 (Support ROS1)
• [x] Issue https://github.com/ros-tooling/setup-ros2/issues/20 (Support ros1_bridge)

This PR requires rework since it depends on feature requests to action-ros2-ci. I'm closing this PR and adding the work required to the AWS backlog.
