Is there any way to move forward with the backports without breaking the ent builds/tests?

Is there any way to move forward with the backports without breaking the ent builds/tests?

I've opened the teleport.e backport and will only merge this one once the enterprise backport is approved, that should minimize the time the build is broken.

The only change in this PR that breaks the tests/build is renaming ClusterFeatures to clusterFeatures. I can undo that and, once the teleport.e PR lands, I can open a new PR to make it unexported again. That is more work but won't break the build, is that preferable to breaking the build for a few minutes?

[rosstimothy]

It's always preferable if changes across oss and ent can be coordinated in a way that doesn't break the build, even if the break is only for a short period of time.

@rosstimothy thanks, I've pushed a commit 111a174 that will prevent the teleport.e build from failing. Once the enterprise PR is backported, I'll create a new PR to revert it.

Thanks @mcbattirola!
