Delete obsolete packages and nodes

[kfunaoka]

Background

Autoware has obsolete packages and nodes. It's hard to maintain them and to understand which packages or nodes are important.

Proposal

Delete obsolete packages and nodes announced in v1.9.0.
https://github.com/CPFL/Autoware/issues/1664

For each package or node:

1. Check carefully whether the package or node is really obsolete
2. Create one pull request to delete one package or node
3. Announce the pull request in Autoware Slack #general channel
4. Review the pull request and wait at least one week
5. Merge the pull request into develop
