Add build test CI using github actions

[Jaeyoung-Lim]

Problem Description This PR adds a build test CI for this repository using github actions.

This adds a nice sanity checks if the chain of catkin dependencies are being broken and if we need to start fixing dependency versions.

While adding the PR the following was added

• Simulation dependencies seems to be broken and ill configured for rosdep installations. Since they are also not part of the dependency list, I think it is more sensible to remove them by default from the package.xml and add them as optional. I have separated the commits to show that the dependencies are broken for the simulation
• grpc is a dependency of protobuf_catkin but was not part of the dependency list and was not getting pulled
• The build test runs both ROS Melodic(Ubuntu Bionic 18.04) and ROS Noetic(Ubuntu Focal 20.04), but Noetic fails due to voxblox not supporting ROS Noetic. This is due to pcl requiring c++14 and higher and is being addressed in https://github.com/ethz-asl/voxblox/pull/379

Since the build is not automatically triggered in the ethz-asl organization from forks, you can see the build results in https://github.com/Jaeyoung-Lim/mav_active_3d_planning/pull/1

Additional Context

• The build is configured to only be triggered by new merges and pull requests

@Schmluk Thanks!

@Schmluk Voxblox and protobuf_catkin now supports ROS Noetic and therefore re-enabled Noetic build for this repo

• https://github.com/ethz-asl/protobuf_catkin/pull/38
• https://github.com/ethz-asl/voxblox/pull/383

@Schmluk I don't have merge rights! :sweat_smile:

Interesting I thought you should be allowed to once the PR is approved. I merged the PR and added you to the repo as a maintainer for the future :)
