[DISCUSS] Deprecate tests based on junit-benchmarks

[Stephen Mallette <sp...@gmail.com>]

Since Ted set up gremlin-benchmarks I'd like to put us on the path to
remove dependency on junit-benchmarks which is still in gremlin-server and
gremlin-test. I recommend that we deprecate the various performance suites
in both modules. My sense is that few providers are relying on those suites
for performance testing so I doubt this change will have much impact when
we eventually remove these classes/dependencies at some point in the future.

I'll assume lazy consensus and move forward on deprecation unless I hear
some objection in the next 72 hours (Thursday April 28, 2016 at 8:15am EST).

Thanks,

Stephen
