Change auto-flush time interval in all clients to 1sec

[yurishkuro]

For some reason we set it to 10 seconds in some libs. This is an umbrella issue to check that all clients are sending at least every second (they will send more often if the data exceeds 64k)

In Java it's already 1000ms https://github.com/jaegertracing/jaeger-client-java/blob/master/jaeger-core/src/main/java/com/uber/jaeger/Configuration.java#L418

public static class ReporterConfiguration {
    private static final int DEFAULT_FLUSH_INTERVAL_MS = 1000;

Same in Python https://github.com/jaegertracing/jaeger-client-python/blob/master/jaeger_client/constants.py#L28

# How often remote reporter does a preemptive flush of its buffers
DEFAULT_FLUSH_INTERVAL = 1
