new register-nodes does not accept ints for numeric input

[James Polley]

Consider the following node definition:

    {
        "arch": "amd64",
        "cpu": 24,
        "disk": 800,
        "mac": [
            "12:34:56:78:90:AB"
        ],
        "memory": 49152,
        "pm_addr": "10.0.0.132",
        "pm_password": "password",
        "pm_type": "pxe_ipmitool",
        "pm_user": "admin"
    }

The previous incarnation of register-nodes would pipe this through jq, something like this:

    stack@bastion:/home/shared$ jq -r '"properties/cpus=" + (.cpu|tostring) + " properties/memory_mb=" + (.memory|tostring) + " properties/local_gb=" + (.disk|tostring) + " properties/cpu_arch=" + .arch' $NODE_JSON
    properties/cpus=24 properties/memory_mb=49152 properties/local_gb=800 properties/cpu_arch=amd64

Because jq explicitly converts the values to strings, the memory, cpu count, and disk figures could all be specified as integers or as strings.

The new register-nodes barfs on the same input:

        BadRequest: Invalid input for field/attribute value. Value: '49152'. Wrong type. Expected '<type 'unicode'>', got '<type 'int'>' (HTTP 400)

This is a backwards-compatibility issue, as peope who have existing nodes definitions that previously worked may find they do not work with the new register-nodes.

    Allow register-node to accept int for input

    register-node used to pipe the nodes definition file through jq, which
    explicitly converts all int values to strings, but the new
    implementation doesn't do so, which is backward incompatible.
