Update code

Simplifies editing the software release by removing the need to edit
instance-erp5-cluster.cf.in each time.
Applied to kumofs, cloudooo, mariadb and zodb.
Partially applied to frontend, as it is more complex.
Not applied to zope, as it is even more complex - but also topical to this
software release.
Also, change default timezone to UTC, to be neutral.
Also, reformat section extension.

Also, replace cloudooo-json by exposing its internals directly.

vincent: Minor fixes. Move branch switch to a separate commit.

Loosened checks are considered safe enough, and the speedup on many-GB
FileStorage files is significant.

Split line more naturally (don't separate switch from related argument).
Use long options instead of abbreviations.

older pod2man does not recognise --errors.
anyway we should just skip make in doc directory.

Buildout output is less scary this way.
