Should be used soon.

There was missing promise from other work.

This is critical feature of SlapOS Master instantiation, and very easy to
damage, thus testing it is important.

It's useful for some tests to use.

Some profiles needs to extends the path with binaries location of provided
software.

This reverts commit 440b88c5

As there might be some reasons why the instance is not found explain what to
in each case.

See merge request !810

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.

See merge request !815

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).

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.

These are old Go releases that were stopped being updated in 2018 - mid
2019:

https://golang.org/doc/devel/release.html#go1.9
https://golang.org/doc/devel/release.html#go1.10
https://golang.org/doc/devel/release.html#go1.11

and that are not used by any in-tree SR or component.

Don't drop Go1.12 and Go1.13 yet: they are too outdated and no longer
supported, but those Go releases are still in use by the following
slapos software:

Go1.12: Caddy, GitLab, Grafana
Go1.13: RepMan, Restic

The maintainers of those software are advised to upgrade to Go1.14 due
to at least recent security fixes in net/http package.

Go1.10 is outdated by today as it was last updated in Jan 2019:

	https://golang.org/doc/devel/release.html#go1.10

Go1.14 is current oldstable - i.e. it is still supported and mature.

As currently no in-tree SR or component use gowork's default, the switch
should not introduce any breakage.

Going Go1.14.3 -> Go1.14.9 brings in many compiler and runtime fixes,
including security fixes to package net/http:

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

Switch helloweb from go1.13 -> go1.14 to test.

Tested on helloworld SR.

Going Go1.13.9 -> Go1.13.15 brings in many compiler and runtime fixes,
including security fixes to package net/http:

https://golang.org/doc/devel/release.html#go1.13

Switch helloweb from go1.12 -> go1.13 to test.

Tested on helloworld SR.

Going Go1.12.9 -> Go1.12.17 brings many fixes including security fixes for
net/http package:

https://golang.org/doc/devel/release.html#go1.12

Tested on helloworld SR.

By copy paste mistake wrong log files were configured for log rotation,
resulting with damaging logrotate for the whole partition.
