master.testnet.solana.com node count is too damn high!

[mvines]

After resetting m.t.s.c, the node count should be exactly 50 (unless somebody is running extra validator nodes attached to m.t.s.c -- possible but unlikely at this point).

After adding 17d927a, it shows a node count of 80 or other numbers not 50.

It's possible we have some kind of crdt table issue.

STR: Look at the output from the latest build at https://buildkite.com/solana-labs/testnet-deploy

@mvines, still an issue?

[mvines]

I suspect it is but we don't have a nice way to detect if/when this happens. I think we could add a --strict flag to bench-tps that turns this expression [1] from a < to !=, then enable --strict on the internal testnets. If it doesn't blow up then this issue can be closed
