software/cloudooo: use slapos.cookbook:switch-softwaretype

Porting to switch-softwaretype involves:

• use recipe slapos.cookbook:switch-softwaretype instead of slapos.cookbook:softwaretype
• don't render software type profiles, only use cloudooo-dynamic-template:rendered instead of ${cloudooo-dynamic-template:rendered}, the profile will be rendered later.
• have a RootSoftwareInstance default alias
• have a part reading parameters using slapos.cookbook:slapconfiguration named slap-configuration. This is what slapos.cookbook:switch-softwaretype expects. Here we renamed the existing part.

At the same time, remove slap-connection that was added as backward compatibility, slapos.core supports this since commit 0fbed0d1 (Migrate slap_connection to slap-connection, and use variables names separated with '-'., 2012-09-18) that was part of release 0.29
