Set cacheSizeGB for 3.2 image about mongodb-container

[php-coder]

Because it uses new config scheme it should be done after #197

BTW, probably, this is also related to https://trello.com/c/tWHmNpY2/895-3-update-mongodb-image-to-autoconfigure-based-on-available-memory-evg33

This is unrelated to that. It is possible to set this using any of the configuration formats.

From the same docs:

To adjust the size of the WiredTiger internal cache, see storage.wiredTiger.engineConfig.cacheSizeGB and --wiredTigerCacheSizeGB.

The old configuration format probably takes wiredTigerCacheSizeGB.

@bparees How it is possible to get maximum amount of RAM in kubernetes/OpenShift?

Postgresql-container uses this group script to get available memory - https://github.com/sclorg/postgresql-container/blob/master/9.5/root/usr/bin/cgroup-limits, but it is failing for me on F25 because of SElinux.

It seems that issue is fixed now, you should be able to read the file again.

Thanks, I see. So same script could be probably a way for MongoDB too. I'll prepare PR.
