Mess with aux properties

[kvaps]

Hi, there is bit mess with aux properties, eg:

linstor n sp --aux foo bar # sets foo property, but 
linstor n sp --aux foo=bar # removes one

linstor n sp Aux/foo bar # doing the same like
linstor n sp --aux foo bar

# but only first variant is allowed for query
linstor n l --prop Aux/foo

# however node list shows 'Aux properties' column with Aux/ prefix: 
linstor n l --show-aux-props

Also I'm not sure if python args allows to modify help message, but I think to specifying positional arguments in first place is most preferred than keys, since keys might have multiple words inside, eg:

usage: linstor resource-group modify name [-h] [-d DESCRIPTION]
                                     [--storage-pool STORAGE_POOL]
                                     [--place-count REPLICA_COUNT]
                                     [--do-not-place-with [RESOURCE_NAME [RESOURCE_NAME ...]]]
                                     [--do-not-place-with-regex [RESOURCE_REGEX]]
                                     [--replicas-on-same [REPLICAS_ON_SAME [REPLICAS_ON_SAME ...]]]
                                     [--replicas-on-different [REPLICAS_ON_DIFFERENT [REPLICAS_ON_DIFFERENT ...]]]
                                     [--diskless-on-remaining [DISKLESS_ON_REMAINING]]
                                     [-l LAYER_LIST] [-p PROVIDERS]

In #32 (comment) @rp- said :

Just note, the errors from the first comment (even while they are still broken otherwise) are because of how the python parser works, you would have to set the opional argument at the end, like:
linstor rg m test --place-count 2 --replicas-on-same room --replicas-on-different rack

I think this is valid for any other commands, eg linstor r c

Just short node the help command is not valid anymore:

usage: linstor resource create [-h] [--diskless] [--node-id NODE_ID] [--async]
                               [--nvme-initiator] [--drbd-diskless]
                               [--storage-pool [STORAGE_POOL [STORAGE_POOL ...]]]
                               [--auto-place REPLICA_COUNT]
                               [--do-not-place-with [RESOURCE_NAME [RESOURCE_NAME ...]]]
                               [--do-not-place-with-regex [RESOURCE_REGEX]]
                               [--replicas-on-same [REPLICAS_ON_SAME [REPLICAS_ON_SAME ...]]]
                               [--replicas-on-different [REPLICAS_ON_DIFFERENT [REPLICAS_ON_DIFFERENT ...]]]
                               [--diskless-on-remaining [DISKLESS_ON_REMAINING]]
                               [-l LAYER_LIST] [-p PROVIDERS]
                               [node_name [node_name ...]]
                               resource_definition_name

eg try to run on v1.1.1:

linstor resource create -s DfltDisklessStorPool m1c7 one-vm-563-disk-0

now this is only valid case

linstor resource create m1c7 one-vm-563-disk-0 -s DfltDisklessStorPool
