Control reporting actions before end of elaboration

[jdscheid]

I would like to control report actions during initial phases, before the end of elaboration. By default, ovm_report_handlers are initialized to a fixed behavior (set_defaults) which is not directly configurable. It looks like the set_report_*_hier operations works recursively over children, who won't exist until after build(). For example, how can I universally set OVM_INFO to OVM_NO_ACTION and have it take effect during the early phases?
