Issue Summary

Starting 7.0.3 Reinstalling Discovery agents with same token breaks connectivity between Discovery tool and Agent.

An error "Stopping AgentClient to xxx.xxx.xxx.xx:xxxxx. Reason: Invalid network message signature. Message is corrupted or invalid agent token was specified." is thrown at the discovery tool as Discovery agent sends a unique token to discovery tool and reinstallation creates a mismatch. This scenario can be solved by regenerating discovery token (Which needs to be replaced on all the running agents)

A feature to revoke the token for a specific agent will be handy for customers with large number of agents installed.

Workaround (Any one of the below options )

• Create a new token on discovery and update them on agents 
• Issue is not observed on 7.0.1
• When uninstalling agent, don't delete the agent installation directory.
