Lima: Detection of features (eg ROI collections)
Bliss detects whether a Lima feature is available with a given LimaCCDs DS by detecting if the feature (sub-device server) is registered in the database. This works fine when upgrading Lima (with new features). When downgrading Lima, the feature remains in Tango DB and Bliss considers that the feature is still available. A better logic would be to check if the sub-DS is exported.
Workaround when downgrading Lima: remove the features (sub-device server) that are not available from the Tango DB, e.g. downgrading from Lima v1.9.18 -> 1.9.6, remove roi_collections DS from Jive.
