Subject: [PATCH] Add memory limits to neo4j deployment

I cannot increase the memory above "2G" without getting an error that no
node has capacity for it. So I believe we have to change the kubernetes
cluster if we want to assign more memory to neo4j.

The other settings were suggested to me by neo4j-admin memrec:
