title: used-defined verbosity level (alias) for UVM reporting (using uvm_info)
body: <p>In UVM, there are pre-defined verbosity levels:</p>
  
  <ul>
  <li>UVM_DEBUG</li>
  <li>UVM_FULL</li>
  <li>UVM_HIGH</li>
  <li>UVM_MEDIUM</li>
  <li>UVM_LOW</li>
  <li>UVM_NONE</li>
  </ul>
  
  <p>Actual reporting can be controlled using command line argument, e.g. +UVM_VERBOSITY=UVM_LOW</p>
  
  <p>(1) Is there a way to have user-defined verbosity levels (or at least
      aliases)?</p>
  
  <ul>
  <li>Like e.g. "UVM_INFO" with same priority as UVM_NONE</li>
  </ul>
  
  <p>(2) Is it possible to create completely user-defined verbosity level, with <strong><em>different</em></strong> priority ?</p>
  
  <ul>
  <li><p>Say something <strong><em>between</em></strong> UVM_NONE and UVM_LOW</p></li>
  <li><p>And, how to control such thing from CLI ??</p></li>
  </ul>
  
  <p>Reason for this is that even with UVM_LOW some commercial VIP is still rather verbose. If possible, I would like to have a "level of my own" for some testbench elements...</p>
