Description

The python console's sendMethodRequest() should handle some cases where the number of arguments supplied do not match the number of arguments required by the schema.

When there are too many arguments supplied, the assumption is that the client is aware of a new argument, but the broker isn't. This is currently the case when qpid-route is dealing with an older broker and calls link.bridge(). The console will look for a named argument that was supplied, but isn't in the broker's schema. If one is found, it is removed. This requires that the new argument be named when it is passed to console. Otherwise we would have to assume the last argument supplied was the extra one, and that would be risky.

When there are too few arguments supplied, the assumption is that client is out of date and isn't aware a new argument that the schema requires. This is currently the case when an old qpid-route is dealing with a new broker and calls link.bridge(). The console will look for arguments in the schema that have default values (starting at the end of the schema). If one is found, it is added with the default value. This requires that all new arguments be given a default value in the schema.
