1. broker: drop munge encryption on event overlay …

   Problem: flux-core's munge dependency is inconvenient
   for spack users building single-user flux, because
   the socket path in munge client library and server
   can easily be mismatched.
   
   Munge is only needed to provide privacy for EPGM
   event distribution, which is not generally used since
   event distribution defaults to the TBON.  Munge was probably
   not the best choice anyway, given the RTT to the munge
   daemon for every message - encrypting with libsodium would
   be better.
   
   Disable encryption of PUB/SUB messages for the time being
   to resolve the inconvenience.  Revisit when EPGM is deployed
   for the system instance.

12. broker: drop code for managing event socket …

    Drop the code from the broker that routed events
    over a specialized event socket, and the "muting"
    of TBON event distribution once that other event
    distribution method became active.
    
    TBON is the only event distribution method now.
