We need slapos script from slapos.core, which is a dependency of
erp5.util

Since using apache-2.4[1] the Include directive will fail if no glob
matches, this switch to new, IncludeOptional[2], available since 2.4, in
order to not fail if no configurations are present.

On some machines, net:TestDialTimeout never passes and today, Go 1.4 is only
used for bootstrapping, so let's not be more clever than Go devs, who
explicitly state to use make.bash

Version up for golang from go1.9.1 to go1.9.2

@rafael @kirr @alain.takoudjou

[ kirr: from https://golang.org/doc/devel/release.html#go1.9.minor

go1.9.2 (released 2017/10/25) includes fixes to the compiler, linker, runtime, documentation, go command, and the crypto/x509, database/sql, log, and net/smtp packages. It includes a fix to a bug introduced in Go 1.9.1 that broke go get of non-Git repositories under certain conditions. See the Go 1.9.2 milestone on our issue tracker for details.

@gabriel says they tested go1.9.2 on Caddy ]

9b5d8262 (v↑ zodbtools (0.0.0.dev4)) added zodburi and in turn ZEO
dependency to neoppod/software-common.cfg because zodburi currently
non-optionally requires ZEO.

However I forgot to notice that if we always pin ZEO to 4.x it will
require `transaction < 2` and this will break neoppod/software-zodb5.cfg
which requires ZODB 5.x and in turn `transaction >= 2`:

	Installing neoppod.
	Version and requirements information containing transaction:
	  [versions] constraint on transaction: 2.1.2
	  Requirement of ZODB==5.3.0: transaction>=2.0.3
	  Requirement of transaction>=2.0.3: zope.interface
	  Requirement of ZEO: transaction<2.0.0
	While:
	  Installing neoppod.
	Error: The requirement ('transaction<2.0.0') is not allowed by your [versions] constraint (2.1.2)

We already have ZODB = 4.x in software-common.cfg and software-zodb5.cfg
overrides it to ZODB = 5.x, but ZEO was left not-overwritten and this
way there becomes conflicting requirement on transaction.

Fix it by also overriding ZEO in software-zodb5.cfg

[golang14] fix TestParseInLocation test: Install package from latest changes on upstream go14 branch

https://github.com/golang/go/commit/4d5426a570c2820c5894a61b52e3dc147e4e7925

golang14 is still failing to build on some server, the commit above fix the
problem on test TestParseInLocation. This is why we install golang14 from upstream go14 branch.

We provide neotest SR which builds current NEO/go together with the
tools which are needed to run the benchmarks.

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.

An example run output could be seen here:

With benchstat (https://godoc.org/golang.org/x/perf/cmd/benchstat) it can be summarized or compared to another run. Here is e.g. summarization:

(was applied separetely as 1b540151).

Please see details in the individual commit messages.

P.S. the results are noisy becuase under regular webrunner I do not have root and cannot run e.g. `cpupower frequency-set -g performance`.

just-introduced in previous commit gowork infrastructure.

The SR does not yet provide automated service to run the tests

However with present state it provides all the infrastructure for people

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
