also reorganise the build to use latest golang

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

stack/erp5: version up APacheDEX 2.0 (py3 only)

This reverts commit 6c399134.

This now supports producing html reports directly

nbd2-host and nbd2-port are asserted too.

Test are reorganized to easily assert mixed scenarios.

Zope no longer serve XML-RPC in ERP5, unless it is explicitly enabled
using this.

See nexedi/erp5!1931

--enable-readline is broken:
  - it searches for readline.h instead of readline/readline.h
  - it does not abort when it fails to find headers
Use --with-readline-inc so that it sets HAVE_READLINE.

Also use the dedicated configure option to enable update limit.
And sqlite3 does not depend directly on ncurses.
