We provide neotest SR which builds current NEO/go together with the
tools which are needed to run the benchmarks. Go part uses
just-introduced in previous commit gowork infrastructure.

The SR does not yet provide automated service to run the tests
automatically periodically and to upload the results to ERP5 (all marked
as TODO).

However with present state it provides all the infrastructure for people
to try to run NEO tests in their webrunner: a `neotest` program is
installed in buildout top-level bin/ . One should use it to run the
tests.

For example:

	Neotest is a tool to functionally test and benchmark NEO.

	Usage:

	        neotest command [arguments]

	The commands are:

	        bench-local     run benchmarks when client and server are both on the same localhost
	        bench-cluster   run benchmarks when server is local and client is on another node

	        run-client      run client benchmarks against separate server
	        bench-disk      benchmark local disk (already part of bench-{local,cluster})
	        bench-cpu       benchmark local cpu  (already part of bench-{local,cluster})

	        deploy          deploy NEO & needed software for tests to remote host
	        deploy-local    deploy NEO & needed software for tests locally

	        info            print information about a node
	        info-local      print information about local deployment

	Additional utility commands:

	        cpustat         run a command and print CPU-related statistics
