PingPong client abstracts the core Redpanda functionality and checks its basic invariant: the client writes a random key/value pair, gets an offset and then reads the log until it sees the written record or times out when it isn't found
Replaces ad hoc ping-pong check with ping-pong client. The client maintains a connection so when we invoke ping-pong 128 times it initializes a producer (init_producer_id) only once. The change reduces test_follower_isolation execution time from 6 minutes to 30 seconds.
