URL: https://github.com/apache/accumulo/issues/4882

   **Is your feature request related to a problem? Please describe.**
   
   Accumulo has functionality to clean up empty tablet server, scan sever, and 
compactor lock nodes in zookeeper.  Well there is functionality for tablet 
servers to do this, not completely sure about compactors and scans severs.  
There may be no test to ensure this cleanup happens.  In dynamic environments 
like Kubernetes there may be lots of host port pairs that are only used once 
and if those are never used again and never cleaned up, then it would leave 
junk in zookeeper.
   
   **Describe the solution you'd like**
   
   Determine if there are test and if not add them.  Also need to determine 
which server components have this cleanup functionality implemented.  Could 
test the implemented functionality and open issues about missing functionality.
