cluster-template-update doesn't work for "labels"

[yatin]

Reproduction step:-
1) create a cluster-template
2) magnum cluster-template-update <cluster-template name or id> replace labels="key1=val1"

Error:-'ERROR: A dict is required in field labels, not a unicode'

The labels should be allowed to update:

magnum cluster-template-create handles(creating a dict from key value pair because magnum api expects a Dict for labels) using magnum.common.utils.handle_labels but magnum-cluster-update doesn't care for labels(creating a dict from key, value pairs)

    Now cluster-template-update works for "labels"

    Now we are handling the label values converting them as a dictionary.
    But as magnum-api only accepts the input as string. We are converting
    the dictionary into string and passing to magnum-api. It is parsing
    the string to dictionary and storing the label value a dictionary.
