…rpc#32093) (grpc#32121)

Apparently there's a difference between bash 3 and bash 4. OSX comes with bash 3 out-of-box, so for whoever wrote this logic it "worked on my machine".

The `((` construct returns a 0 exit code if the value is non-zero. Since the value starts at 0 and we do a post-increment, it will always fail the first time. Changing it to a pre-increment should fix it.

xDS interop: resume circuit_breaking test (grpc#32038) (grpc#32055)

This is a test running on legacy (GCE) framework.
It was disabled in grpc#27355,
however it has never been ported to the new framework.
Unless there were reasons I'm not aware of, disabling it is a mistake.
Other languages still run it:

- Go: https://github.com/grpc/grpc-go/blob/f2fbb0e07ebf3dd46aa641ee89c9f17e8083eaf6/test/kokoro/xds.sh#L30
