Support for user defined ports via DOCKER_RIAK_BASE_HTTP_PORT

The default port config is -P, which means that docker with assign
arbitrary ports for riak to use.  These are usually in the 49xxx range.

if DOCKER_RIAK_BASE_HTTP_PORT is set, then we will manually forward
port number $DOCKER_RIAK_BASE_HTTP_PORT + $index to 8098
and forward $DOCKER_RIAK_BASE_HTTP_PORT + $index + $DOCKER_RIAK_PROTO_BUF_PORT_OFFSET to 8087
DOCKER_RIAK_PROTO_BUF_PORT_OFFSET is optional and defaults to 100

example usage:

DOCKER_RIAK_BASE_HTTP_PORT=8800 DOCKER_RIAK_AUTOMATIC_CLUSTERING=1 DOCKER_RIAK_CLUSTER_SIZE=5 make start-cluster
