As there might be some reasons why the instance is not found explain what to

Thanks to using check_execute_command with logrotate -d one can assure, that
logrotate is for sure correctly configured.

By disabling delaycompress filenames are going to be stable, on delaying the
compression is not needed.

In some cases there is not need to have delayed compression of the logs.

By using regular expressions, matching exact host names up to the optional
port and putting wildcard matches in the end, the Haproxy acl rules will allow
to direct request to correct backend.

Because of escaping of slapos.cookbook:wrapper kedifa is never reloaded, so
use instead jinja2 with template_wrapper for it.

Also adapt to kill from dash (-HUP).

Update lab.nexedi.com/kirr/neo.git and lab.nexedi.com/kirr/go123 to latest.
Update all other go packages.

The update puls in the following new dependencies:

    github.com/shamaton/msgpack
    github.com/tinylib/msgp
      github.com/philhofer/fwd
      github.com/ttacon/chalk
      golang.org/x/mod
      golang.org/x/xerrors

    github.com/davecgh/go-spew
    github.com/pmezard/go-difflib
    gopkg.in/yaml.v3

Going from 0.0.0.dev4 to -> 0.0.0.dev7 zodbtools:

- Stabilized `zodb dump` format and layed ground for `zodb restore`;
- Taught `zodb analyze` to work with any ZODB storage (instead of being
  FileStorage-only tool) and to analyze a particular range of history
  (instead of crunching data for days on a large database);
- Added `zodb commit` tool that is handy in testing.

Since zodbtools started to depend on pygolang, remove the conflicting,
and now unneeded, explicit pygolang pin from neotest.

This partially reverts commit 20fb7c58.

Unfortunately having trustable X-Forwarded for in case of SlapOS Master
is not so simple, and not needed for now, as the approach is a bit different
on that apache, thus let's revert for now.

The update of AddOutputFilterByType is kept.

And not globally inside slapuser $HOME (which is go builtin default).

Explanation:

- Starting from Go1.10 the go command maintains cache for built packages, test results, etc:

  https://golang.org/doc/go1.10#build

  while this cache tries to remember by which go version and in which
  environment a package was built, and reusing the cached entry only when it is
  indeed correct to do so, by keeping this cache in a shared place - not per go
  workspace - we expose it to interactions with other go installments, which,
  due to e.g. software bugs might misbehave.

  -> keeping the build cache inside go workspace makes things more safe.

- Starting from Go1.13 the go command allows to keep its configuration and environment inside a file:

  https://golang.org/doc/go1.13#go-env-w
  https://go.googlesource.com/proposal/+/master/design/30411-env.md

  The default location for such file is per-user, which can bring
  misinteraction among several go workspace installments and wrt system go
  installment.

  -> move this configuration file into inside go workspace.
