Delete crdt-example.proto

[pjfanning]

I ran sbt interop-tests/test and this file wasn't needed

• see this description on add license details for proto file #162 for why it is useful to get rid of this file

So I just had a quick glance at the code and I am getting the impression that this is meant to be an example file, in which case its fine to delete but maybe we should make a reference to the file in our documentation somewhere?

• it is checked into a test project
• my impression is that it was meant to be part of the testing of a PR but then it wasn't used
• if we were to document where you find example protos - what page would it go on? If we have no such page, would we create a page with just this proto?
• can't we add docs at any time?
• this file is a potential -1 in our release

this file is a potential -1 in our release

Yeah I am not blocking the deletion of the file, I just find it odd that there is a random source file that isn't even used hence my assumption is that it was meant to be some example file.

Ill approve the PR but can we make an issue on this, i.e. something along the lines of "Figure out what role crdt-example.proto had?"
