Fixup of a3e15fc4.

Before this patch SlapOS users had to manually add SSL files in case WCFS
was used in combination with NEO+SSL. This is bad as we can easily forget
to update local parameter files when updating instance parameters ("_ca",
"_cert" and "_key"). This builds up on nexedi/slapos@706801f2.

NEO/go doesn't understand what it should do with these parameters and
raises an error in case they are added to the NEO URI [1].

'wendelin.core' needs to differentiate between a NEO cluster with SSL
and without SSL from a normalized zurl (e.g. a zurl which doesn't
contain any paths to encryption files). Therefore the 'neo' / 'neos'
scheme difference was introduced in nexedi/neoppod@bc3e38ea.
This patch introduces this difference in zurl that SlapOS provides for
'wendelin.core' - this essentially fixes a ERP5+WCFS setup that connects
to a NEO cluster with activated SSL.

We only need one query identifier ('?'), while query options should be
separated by the separator identifier ('&'). This essentially changes
the resulting NEO URI from

  neo://cluster@IP&a=b?b=c

to

  neo://cluster@IP?a=b&b=c
