rbd: add check for imageFeatures parameter

Browse Source 
This commit adds checks for missing `imageFeatures` parameter
in createvolumerequest and nodestagerequest(only for static PVs).
Missing `imageFeatures` parameter is ignored in case of non-static
PVs to ensure backwards compatibility with older versions which
did not have `imageFeatures` as required parameter.
