Now I'm starting to implement cli client for KeyValue Storage service MagnetoDB.<br>
I'm going to use heat approach for cli commands, e.g. heat stack-create --template-file <FILE>,<br>
because we have too many parameters to pass to the command.<br>
For example, table creation command:<br>
<br>
magnetodb create-table --description-file <FILE><br>
<br>
File will contain json data, e.g.:<br>
<br>
{<br>
    "table_name": "data",<br>
    "attribute_definitions": [<br>
        {<br>
            "attribute_name": "Attr1",<br>
            "attribute_type": "S"<br>
        },<br>
        {<br>
            "attribute_name": "Attr2",<br>
            "attribute_type": "S"<br>
        },<br>
    {<br>
            "attribute_name": "Attr3",<br>
            "attribute_type": "S"<br>
        }<br>
    ],<br>
    "key_schema": [<br>
        {<br>
            "attribute_name": "Attr1",<br>
            "key_type": "HASH"<br>
        },<br>
        {<br>
            "attribute_name": "Attr2",<br>
            "key_type": "RANGE"<br>
        }<br>
    ],<br>
    "local_secondary_indexes": [<br>
        {<br>
            "index_name": "IndexName",<br>
            "key_schema": [<br>
                {<br>
                    "attribute_name": "Attr1",<br>
                    "key_type": "HASH"<br>
                },<br>
                {<br>
                    "attribute_name": "Attr3",<br>
                    "key_type": "RANGE"<br>
                }<br>
            ],<br>
            "projection": {<br>
                "projection_type": "ALL"<br>
