Deprecate tf for tf2

[wjwwood]

This pr deprecates all of the interfaces in rviz which I believe need to be so that in a future version we can drop the dependency on tf completely.

The two main places where interfaces are disabled are:

• VisualizationManager: b1bb6a2
• FrameManager: 7ee47f3

I migrated the MessageFilterDisplay which is a base class that many display plugins inherit from and therefore most of them will require no changes at all. I also migrated a couple other displays to show how it can be done, but I just suppressed the rest of the displays that produced deprecation warnings because I wanted to give an example of how to do that and because the work to convert them can be deferred until we actually remove the dependency on tf completely.

Examples of migrating to tf2:

• MessageFilterDisplay: 0f227e5
• Image related displays (image and camera): ffdfad0
• DepthCloudDisplay: 2dc400d

Examples of suppressing the deprecation warnings:

• GridCellsDisplay: 89b51e7
• TFDisplay: c7f6a4a

There are a few unrelated style/warnings related changes at the end, which I could separate if desired, but they're small and mostly only affect macOS.

@IanTheEngineer FYI

I plan on closing the other pr. Also, this will probably introduce a deprecation warning in moveit (sorry about that), but I'm happy to make a pr for that if you can point me to where you needed to change things there. The warnings are easy to either address or suppress. There are some examples above in the issue description.

I'll also mention that for the changes to the Constructor of VisualizationManager and FrameManager which optionally take a tf::TransformListener, I deprecated them but could not offer the alternative right now. The reason is that if someone gives us a tf2 equivalent I cannot provide the tf version of the client when someone asks for it via getTFClient(). So they'll have to suppress the warning and then when we completely remove tf I can provide a new constructor that can take the tf2 equivalent.

That makes sense. I’m out on vacation this week, but I’ll point you to the right spot to help suppress the deprecation warnings next week when I return (around 5/16). There’s only two lines in all of MoveIt using the FrameManager

The CI looks good to me, the remaining failure is in robot_model_display.cpp and should be addressed separately, see: #1235

I'll add an note on this wiki page when this is merged:
