This reverts commit ee8e3fb2.

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.

If we don't specify MaxRequestWorkers, it seems like Apache 2.4
errors with:
AH03490: scoreboard is full, not at MaxRequestWorkers. Increase
ServerLimit.
Maybe because MaxRequestWorkers then defaults to a too high value
compared to ServerLimit and ThreadsPerChild.

This is useful to being able to peek for low level site result details.

getWorkingSet() is slow and it is not always needed. So, it is better not to call it in __init__.

Revert "slapos/recipe/librecipe/generic.py: GenericBaseRecipe's _ws is a lazy attribute now."

This reverts commit 281d3774.

When git repositories are in detached head, `git symbolic-ref` cannot be used.

In this case, `gowork-snapshot` outputs `fatal: ref origin is not a symbolic ref` and create a buildout profile with empty revisions.

After these changes, we try to get from a remote named origin in this case. If this did not work, we output the problematic repository.

I added some minor "cleanups" at the same time.

because other variables are vertically aligned

When git repository is in detached head, there's no symbolic-ref, so we
cannot anything better that assuming there's a remote named "origin"

This reverts commit 6cb00ff0,
because of a regression in InnoDB (https://jira.mariadb.org/browse/MDEV-14614).
Several functional tests started to fail with 10.2.12.

As currently it fallbacks to system's gettext

While testing this merge request : nexedi/erp5!243

The following test was failing for me : https://nexedi.erp5.net/test_result_module/20180107-664D9A6/13

Since numpy is not added as a dependecy for h5py. the testnode didn't upgraded numpy while upgrading h5py. 
Adding numpy as a dependency should fix it

Fixes all cloudooo being given the same port, because of jinja2 variable
scoping.
Also, move to buildout.hash.cfg for md5sum maintenance ease.

Also update README accordingly.
Its becasue now erp5-site is being created automatically using software-type
default and there is no create-erp5-site software-type anymore.

In the particular case of PATH, '' is the same as '.',
which is a bad idea from a security point of view.
