Release fixes
This merge request fixes several issues discovered at the last minute:
- Fix the velodyne node name (removed the autoware_auto prefix from the executable)
- Use the new parameters API in the ray ground filter and voxel grid downsampling
- Fix the name of the topics for euclidean clustering: subscribe to the same topic as ray ground filter, and use a more descriptive name for publishing
- Reserve capacity for the clusters in euclidean clustering
