get_mountpoint() no longer automagically searches for a mountpoint (Windows incompatible)

SSDM-9543: property 'unarchiving-scratch-share-maximum-size-in-GB' added to share properties and use it to limit the size of unscratch share. unit tests extended.

added some convenience methods to the space object: get_projects, get_experiments etc.

SSDM-9546 : Prevent certain properties to be updated to use the Word Processor on master data updates

small bugfix when search with properties does not return any dataset or sample

fixed duplicate columns, properties are case insensitive
