Jérome reports that Pygolang build on Python3 fails because geventmp turned out to be not pinned:

nexedi/slapos!862 (comment 121359)

Geventmp is indeed used by pygolang only on Python3

nexedi/pygolang@cd67996e

and with Python2-only testing I missed to handle it.

-> Fix it and add test for pygolang/py3.

Rst files that persistent wants to use from tests are not installed along with regular egg.

Globbing can be unreliable after incremental profile update and rebuild because
buildout does not remove old eggs. Also it is much more clean to be precise.

-> Use [python-interpreter] to build bin/python with sys.path to wendelin.core
and other needed eggs.

Without referencing component/numpy/ numpy will be installed from just PyPI.

Go1.15 is incremental improvement over Go1.14 with better compiler and runtime:

https://blog.golang.org/go1.15
https://golang.org/doc/go1.15

Don't drop support for Go1.13 yet, as that (no longer supported) Go
release is still being used by replication-manager and restic
components.

Remain default at Go1.14 yet.

Switch helloworld to Go1.15 and test this patch on that
software-release.

Going Go1.14.10 -> Go1.14.12 brings in runtime and security fixes:

https://golang.org/doc/devel/release.html#go1.14

Tested on helloworld SR.

See merge request nexedi/slapos!860

When invoking tests with setup.py test, missing eggs are installed before
running tests, using their latest available version, but we want to always
install eggs using buildout and using pinned versions.

The section template-slapuser-script creates the "bin/slapos" wrapper
which is needed inside runner-import.sh script.

Otherwise it's almost impossible to check for which node statistics are shown.

Fixes 8d5910dc

Limit stats to frontend entries only, as they are the most important for the
frontend operator, and also having thousands of entries makes the stats page
unusable.

fixes 8d5910dc

Despite the introspection has replaced old style Caddy-based log-access, some
bits were not removed, so remove then now.

fixes 0c830c4c

It was done in frontend partition, but missed in kedifa.
