Can't set non-string values via CLI

[Lucas Alvares Gomes]

Some fields in Ironic support multi-type values, for example the "extra" attibute of the resources supports strings and ints in the moment, but via the CLI it's impossible to set non-string values for those fields, see:

stack@vm:~/python-ironicclient$ ironic node-update 8eeb8e5a-936a-49c2-a0d6-11de550a3f5c add extra/int=10
+------------------------+------------------------------------------------------------------+
| Property | Value |
+------------------------+------------------------------------------------------------------+
...
| extra | {u'int': u'10'} |
...
+------------------------+------------------------------------------------------------------+

    Support setting non-string fields

    Some attributes in Ironic support multiple types of data, before the
    CLI was treating everything as a string this patch is changing that by
    making the CLI to JSON deserialize the values before sending it to Ironic.
