Actually this shouldn't be needed, once this CL is merged.

We should wait with merging this, I will upload an updated version of this PR.

Turns out SSH and Git Protocol V2 tests require some special setting, that complicates things on Bazel CI, see:
https://buildkite.com/bazel/gerrit/builds/12701#018bfdc5-4521-4eb1-b4c5-8771b19b5617

I think it's much simpler to take those tests out of the picture on Bazel CI, as trying to fix them.

I've sent you this CL for review.

Could you please review it? Thanks!

@meteorcloudy we clarified the problem with openssh-client.

Could you please look at RBE build breakage? I'm not sure I understand it:

https://buildkite.com/bazel/gerrit/builds/12729#018c15cd-c426-46d9-a8b0-a79c4924240c

It seems, that outdated options pulled in on this platform?
I don't know how/where to fix it?

Should we try to fix it, or should I removed RBE-platform again on Bazel-CI@Buildkite.

We are using RBE@GCP downstream without any issue for years now...

It's from the bazelci.py script, there is some recent change to update the flag names, but was rollbacked for some reason. @fweikert
#1811

The logic is here:

continuous-integration/buildkite/bazelci.py

Lines 2027 to 2034 in 387688a

	for platform_flag, value in list(platform_flags.items()):
	found = False
	for original_flag in original_flags:
	if original_flag.startswith(platform_flag):
	found = True
	break
	if not found:
	flags += [platform_flag + "=" + value]

@meteorcloudy Thanks for the pointer. I filed this issue for this platform and will remove it for now for gerrit pipeline, and reconsider to re-add the build on RBE platform later, once it's fixed.
