slapos.recipe.cmmi executes command lines by line, so this build options
were ignored.

version up : OpenBLAS 0.2.15. First try with auto-detected target and if it fails try TARGET=GENERIC.

You can also spcify the target explicitly by build-ext-options.

This description is required when requesting more than one zope partition
sharing a given IP (ex: webrunner-type setup).

- There's now a single software type 'neo' (in addition to the default)
  which contains:
  - 1 master
  - 1 admin
  - a configurable number of storage nodes, that share the same MySQL server
- Review of parameters to configure MySQL server.
  (innodb_buffer_pool_size is important)
- Check of meaningless values of 'replicas'.

This reverts commit bf75e8a9.
