these were already defined in stacks and were different here for no
apparent reason.

This is longer needed since years, also the part looks broken.

Reintroduce a patch to fix build error:

    execvp: printf: Argument list too long

that seems to happen again with nodejs 16.

Also add a note for minimal supported version, that will have to be
set in software

This contain the fix for go 1.16 that we backported, so we can use
upstream repository again.

No effort has been made to keep data compatibility, updating instance
probably does not work

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"

One notable change since previous version is that a new sql input,
that can be used to get metrics from sql queries.

This partially reverts ee733f9d because
of issues with python3

Commit ee733f9d (version up: zc.buildout 2.7.1+slapos017,
slapos.libnetworkcache 0.23, 2022-03-28) introduced a new way of
computing cache key used for shacache and downlaod URLs that were only
in cache but no longer available from their original location no longer
could be retrieved. This update the original download URLs to URLs that
are valid today.

I could not find tarball for 2.1 so I updated
