In our production notes we recommend setting:
vm.max_map_count value of 128000
This corresponds to our default max connections of 64k, as each connection requires 2 maps.
Upon startup, the mongod should check this value (/proc/sys/vm/max_map_count) and warn if it doesn't equal 2*max connections.
Acceptance Criteria: We warn users that vm.max_map_count doesn't exceed 2x max connections
