DB-API allows changing UUID for Node, Chassis and Port

[Dmitry Tantsur]

DB-API allows changing UUID for Node, Chassis and Port. There is even a unit test on changing a Chassis UUID. I think it's a vague "feature", because users will expect UUID to be kind of primary key (we don't disclose real pkey) and won't expect them to change. DB-API should explicitly forbid this behavior, raising InvalidParameterError.

Not impact on end user features, as it's impossible to change UUID via client.

    Prevent updating UUID of Node, Port and Chassis on DB API level

    UUID is seen as something similar to pkey and is not expected
    to be updated after creation.
    This patch makes update_{node,chassis,port} raise InvalidParameterValue,
    if 'uuid' field is passed in.
