We stop using slapos.recipe.build:cpan , but these unstable components are
not ready and not being actively maintained, so move them inline in
mioga software, which was the only user of these components.

When the work on this is resumed, we should switch to perl-CPAN-package
here as well.

Generate a wrapper with all dependencies available

${perl:location} is now a perl without any package, components using
perl with one specific package must switch to using the perl with the
dependent CPAN packages installed.

Installing everything in site_perl is not the "buildout way" and is
incompatible with the upcoming shared slapos.recipe.cmmi

make sure password section is installed before request runner{0,1} and pbs instance for webrunner because the password is send in the request.

The path of software release in webrunner is like: `/srv/slapgrid/slappartXX/srv//runner/project/slapos/software/soft/software.cfg`  because ~/srv directory in webrunner is set with a / at the end:

Changing that path will modify the URL of software release in webrunner, this is why we should always keep it as: `/srv/slapgrid/slappartXX/srv//`

if backup.signature is present in tmp/ folder (during push) promise will fail because find return 2 elements and 1 is expected

If pull is running, files can be changed and promise will raise. Wait when backup pull
is not running before check signature diff.

Strip earlier, as stripping so late leads to correct self.passwd
but incorrect passwd, thus 3rd party applications storing passwords
with additional newlines are still resulting in bad passwords.

This is a follow-up of commit 30c5367a

We still don't depend on neoppod[storage-importer,tests]
to avoid pulling ZODB3.

This also fixes pinning issue for software-zodb3.cfg
