also reorganise the build to use latest golang

The later is not really supposed to be XML-RPC comptabible and it's
anyway to use ZPythonScript_edit

testing strategy:
 - use an external method with a transaction manager which sleeps
  for 20 seconds during tpc_vote and tpc_commit
 - commit such a transaction
 - stop zope
 - check the stop happens after the tpc_commit

For now this still have to be enabled with a config like this in a .conf
file in srv/telegraf/extra-config/  :

    [[inputs.execd]]
      name_override = "slapos"
      # this needs sudo when using can not access supervisor socket, like when being installed in root slapos
      command = ["/usr/bin/sudo", "$SOFTWARE_DIR/go.work/bin/telegraf-input-slapos", "-config", "/path/to/slapos.conf"]

/path/to/slapos.conf would contain something like this:

    [[inputs.slapos]]
      ## Folder where partitions are located
      instance_root = "/srv/slapgrid/"

      ## filepath.Glob pattern to look for recursive instances
      recursive_instance_glob_pattern = "*/srv/runner/inst*/"

      ## Path of supervisor socket, relative to instance root
      socket_name = "sv.sock"

This version has a new sql input, that can be used to get metrics from sql
queries.

WIP ERP5: XXX dumps() parameter for longrequest promise 🚧

Not sure why it was OK on python2 and not sure if this has to be done
or the promise code needs to cast the results of getConfig()

py3: do not enable NEO test yet 🚧

at this point they all fail after long timeouts, because neo does not
support py3 yet

This reverts commit 6c399134.

This is a fixup of 210e2d76.

Without full diff it's often impossible to understand the problem of JSON
schema introduced by the developer.

Upgrading pygolang in the context of SlapOS brings in some minor speedup
and fixes, but is mostly needed for ors-amarisoft software release due
to fix for a memory leak and optimized timers:

nexedi/pygolang@2ec5e96b
nexedi/pygolang@044deb35

The full list of the changes is below:

Similarly to wendelin.core (see ad34ff4a "wendelin.core: Always use git
checkout for both release and development version") let's switch pygolang to
install via git checkout for both release and tests.

This way we avoid dependency on pypi and will be able to do minor updates
without doing bigger to-pypi releases. Always using git checkout also helps
security a bit because we remove reliance on trust to tarball received from pypi.

@jerome reports ue/cell/* schemas are not valid JSON and he is right: in
30179be5 I made a mistake to add extra trailing " after propertyOrder
integer value. Fix that.

  They are json-editor specific features and are not part of the json schema

  By using ref to ../ru/input-schema.json you append oneOf list and dont extend the
  current list.

  This fixes validation properly when oneOf the values are used.
