[foxy-backport] add cyclonedds to the list of rmw using graph info topics (#231)

[mikaelarguedas]

As CycloneDDS security has been made available in Foxy (and synced to main already)

I see that cyclonedds is using release/0.7.x in foxy, but if I look at the changelog there I don't actually see security-related things. I do on master, but that's not what's in Foxy. I'm obviously missing a piece of the puzzle, can you show me?

but if I look at the changelog there I don't actually see security-related things.

I guess the missing piece is that the changelog on the 0.7.X branch is missing the 0.7.0 entry (which is somehow ironic).
The one on master has the changelog of version 0.7.0 which is the one that's in Foxy and includes the bits about security support.

Ah I should have looked at rosdistro, okay fair enough, thank you. Great to see this come to Foxy!

Opened a PR against the changelogs to avoid future confusion

The ROS buildfarm CI failure is due to connectivity issue updating rosdep database and is unrelated to this change
