Default memory high watermark to 1.0 when using a higher value Prior to this change, setting the vm_memory_high_watermark to a value higher than 1 (inclusive), would default to 0.4. This is different from the behaviour when setting an absolute value, namely defaulting to the total memory available. Extracted common memory-related macros & records so that they can be shared by tests. re rabbitmq/rabbitmq-server#1285 [finishes #148470947]
