Adding custom tags for instances created

[Lahiru Sandaruwan]

Hi,

I have a requirement to add tags to the instances created through cloud
controller. jclouds supports tags already.

Since we have to support several tags, we will not abe to support them at
properties.

How about cartridge definition with iaasProvider like following(Adding
optional 'tag' element),

    "iaasProvider":[
         {
            "type":"ec2-west",
            "imageId":"us-west-1/ami-2a39076f",
            "maxInstanceLimit":"5",
            "property":[
               {
                  "name":"instanceType",
                  "value":"m3.medium"
               },
               {
                  "name":"keyPair",
                  "value":"r2-azdev1"
                }
            ],
            "tag":[
               {
                  "name":"name",
                  "value":"DEV Stratos"
               },
               {
                  "name":"owner",
                  "value":"Lahiru"
                }
            ],

         }

send your thoughts over.

Thanks.
