[README] docker run ... incorrect

[DazWilkin]

Both docker run (agent|collector) appear incorrect:

docker run --rm -it -p 55678:55678 -p 55679:55679 \
    -v $(pwd)/ocagent-config.yaml:/conf/ocagent-config.yaml \
    --config=/conf/ocagent-config.yaml \
    ocagent

The --config flag applies to the ocagent and must follow the ocagent container reference:

docker run --rm -it -p 55678:55678 -p 55679:55679 \
    -v $(pwd)/ocagent-config.yaml:/conf/ocagent-config.yaml \
   ocagent --config=/conf/ocagent-config.yaml

Please also consider defaulting to long flag names where available to aid comprehension:

docker run \
--rm \
--interactive \
--tty \
--publish=55678:55678 --publish=55679:55679 \
--volume=$(pwd)/ocagent-config.yaml:/conf/ocagent-config.yaml \
ocagent --config=/conf/ocagent-config.yaml
