title: Remove User in snmp by agent
body: <p>I could quickly go through the snmp installation and it works fine.</p>
  
  <p>In one of the agent modules I am currently looking into and trying to modify the source. I came across an issue where I need to remove the user by the agent.</p>
  
  <p>Stuck with to complete this:</p>
  
  <p>Just like the way <code>net-snmp-create-v3-user</code> creates an user at server side I was wondering if there is something similar to remove the user.</p>
