In looking at ACCUMULO-3772, I'm seeing loads of the following:

The log message spam is annoying, but I think it's also indicative of a large problem where
we are repeatedly re-creating the same ClientConfiguration object over and over again. This
is wasteful and unnecessary as the contents of the ClientConfiguration can be static for the
lifetime of the server process.

Need to identify if ClientConfiguration objects are being repeatedly created in the server
processes (potentially via AccumuloServerContext) and fix the calling code to avoid the annoying
log message over and over.
