This will also make it possible to access paragraph results easily using
the z-variable interpolation feature of various interpreters. So a simple
command like `%sh echo {population-table}` will retrieve and display a
previously saved (population-table) result (if interpolation is enabled for
shell).
But a crafty user will be able to disrupt
https://issues.apache.org/jira/browse/ZEPPELIN-3596 by using a resourceName
compatible with ZEPPELIN-3596's syntax for {...}
