proxy: fix flaky TestSlowService (#2528)
backendTimeout("1ms") in TestSlowService may cancel context during
dialing which results in i/o timeout error and 502 response status

$ go test ./proxy -run=TestSlowService -count=10000 | grep -F 'FAIL:' -C1

Increase TestSlowService filter parameter to 10ms.
Also make requests using test proxy client.
