Jason Tedor 13e20e3320 Set external nodes to default to 512m of heap
This commit sets external nodes for integration tests to default to
using 512m of heap. This can be overridden using tests.heap.size (a
system property that we already use elesewhere for setting the size of
the heap for the test runner) or using tests.jvm.argline (this last one
takes precedence).
