Use better default memory allocators
We have settled on the following configuration for memory
allocators after testing many different combinations:
+MBas ageffcbf +MHas ageffcbf +MBlmbcs 512 +MHlmbcs 512 +MMmcs 30
They reduce the memory usage and help RabbitMQ reclaim memory,
at the cost of a slight decrease in performance due to an
increased number of memory operations.
We need to start Erlang with these values in order to figure
out whether they are supported. The allocator strategies we
recommend were introduced in Erlang/OTP 20.2.3. The values
can be overriden using RABBITMQ_SERVER_ERL_ARGS.
