How to Add an `rcap.max-rss` Attribute for a Project

Assume the root role.
Add this attribute to the /etc/project file:
```
rcap.max-rss=value
```

Example 2 RSS Project Cap

The following line in the /etc/project file sets an RSS cap of 10 gigabytes for a project named db.

db:100::db,root::rcap.max-rss=10737418240

Note that the system might round the specified cap value to a page size.
