It was used in only 2 places and createPythonScript has no equivalent
(maybe reusing 'initialization' from easy_install would produce something
readable enough). For the moment, let's drop this parameter, so that
createWrapper can switch to Python wrappers for complex cases.

There was an inconsistency between the 2 ways of creating executable wrappers:
- createWrapper: parameters-extra defaults to False
- slapos.recipe.librecipe.execute.generic_exec: no option, enabled

An option for that is not worth the effort.
Let's always enable even if it's meaningless.

/software/ and /stack/ will be cleaned up once a new version of this egg

The workaround for shebang size limitation is removed because it's redundant
with what is done by zc.buildout.easy_install and slapos.recipe.cmmi. This also
fix the issue that a process has a bad name even when the workaround is useless.

Using the approach from nexedi/slapos!258 I checked that all dependencies was pinned down.

Some eggs where not pinned, all git repositories seems to be pinned ( I found there was only `[nginx-push-stream-module]`)

neotest: Actually add instance and teach it to run `neotest bench-local` under Nexedi testing infrastructure

Commit 31fe231f (neotest: Draft software-release to run NEO/go & friends
tests/benchmarks under webrunner) added "neotest" software release, but
there it added only software supplying - not instantiation - this way
allowing only manual play with neotest.

Recently @rafael approached me saying that one of my webrunner is red on
monitoring because "neotest" software inside fails to instantiate, and
suggested to create a simple instance with bin/runTestSuite inside, so
that this way neotest could be added to a testnode and run on regular
basis by our testing infrastructure.

So here it goes - simple instance with only bin/runTestSuite which tries
to adhere to testnode protocol.

Fixups discovered to be needed while running on testnodes are also included in this merge request.

lsblk is needed for neotest. Please see details in individual commit messages.

Similarly to coreutils we need recent util-linux because if e.g. a testnode has
old version of it its lsblk does not work to what neotest expects, e.g.:

	lsblk: unknown column: REV,SIZE

For example we need realpath and if base os provides only older coreutils there
is no such utility and neotest fails:

/srv/slapgrid/slappart8/srv/testnode/bct/soft/55158b6a5b027aa40954c3f974d5b3e9/go.work/src/lab.nexedi.com/kirr/neo/go/neo/t/neotest: line 589: realpath: command not found

Fix it by building & hooking into $PATH coreutils by ourselves.

So here it goes - simple instance with only bin/runTestSuite which tries

For the actual runTestSuite program I followed the same approach as for
bin/neotest itself - the main program is not processed via any templates
and is used as it was pristinely downloaded, and all buildout
integration is done via first sourcing $SR/neotest-env.sh .
So bin/runTestSuite inside instance follows this approach.

erp5.util is updated from 0.4.49 to latest 0.4.50 because there were
backward-incompatible changes in 0.4.50 release (2 @luke: which btw will
render neoppod and build-rina runTestSuite(s) broken when they try to
upgrade) and for me it would be a waste of time to later go through
updating for 0.4.49 -> 0.4.50 API change, so I used the latest release
right from start.

lsblk is needed for neotest (see https://lab.nexedi.com/kirr/slapos/commit/7cc37e3c).
However lsblk is built only when the following dependecies are enabled:

	- libblkid
	- libmount
	- libsmartcols

	https://github.com/karelzak/util-linux/blob/v2.31-286-g8e782a839/configure.ac#L1483

we already have libblkid and libmount enabled, but libsmartcols was missing.

Enable it.

While debugging the change this print was useful to know whether the
patch was taken into effect or not, but now it seems to be too chatty in
practice. Let's disable it.

stack/monitor: Add a random delay of maximum 60 seconds to all monitor cron jobs to avoid high load at the first second of every minute.

It is useful to give a random delay on cron jobs.

For example one could want to build the software with race detector,
e.g.

	[gowork]
	...
	buildflags = -race

or if you want to build a plugin for fluent-bit

	[gowork]
	...
	install	   = your.package.import.path
	buildflags = -buildmode=c-shared

and then your package will be installed as shared library into

	${gowork:directory}/pkg/`go env GOOS`_`go env GOARCH`/<your.package.import.path>.a

One could pass that location explicitly to `fluentd-bit -e ...` or
symlink to it from some .so from global directory of fluent-bit plugins.

Maybe it is not very good to use `go install` for building plugins
(instead of `go build -o ...`) but we anyway need to have ability to
specify buildflags as a generic feature, hence this patch.
