Call rosdep install from cloudsim dockerfiles

[peci1]

I guess this is the way to get a catkin workspace correctly up and running. Not utilizing rosdep leads to manual management of several lists of packages, which is highly error-prone.

This IMHO offers a better solution to #731 than #732 (because somebody has already specified that subt_ros package depends on compressed_image_transport as an exec dependency).

I tried building the Dockerfiles and they both build fine.

In cloudsim_sim image, the rosdep call installs:

executing command [sudo -H apt-get install -y ros-melodic-joint-trajectory-controller]
executing command [sudo -H apt-get install -y ros-melodic-controller-manager]
executing command [sudo -H apt-get install -y ros-melodic-diff-drive-controller]
executing command [sudo -H apt-get install -y ros-melodic-multimaster-launch]
executing command [sudo -H apt-get install -y ros-melodic-interactive-marker-twist-server]
executing command [sudo -H apt-get install -y ros-melodic-lms1xx]
executing command [sudo -H apt-get install -y ros-melodic-teleop-twist-joy]
executing command [sudo -H apt-get install -y ros-melodic-joint-state-controller]

In cloudsim_bridge, it installs:

executing command [sudo -H apt-get install -y ros-melodic-joint-trajectory-controller]
executing command [sudo -H apt-get install -y ros-melodic-controller-manager]
executing command [sudo -H apt-get install -y ros-melodic-diff-drive-controller]
executing command [sudo -H apt-get install -y ros-melodic-multimaster-launch]
executing command [sudo -H apt-get install -y ros-melodic-interactive-marker-twist-server]
executing command [sudo -H apt-get install -y ros-melodic-lms1xx]
executing command [sudo -H apt-get install -y ros-melodic-teleop-twist-joy]
executing command [sudo -H apt-get install -y ros-melodic-joint-state-controller]
