QPIDJMS-267 Failover discovery via connection properties
Add support for discovering new failover URIs bsaed on redirect
style Maps in a list provided in the Open frame of a remote peer.
Allow for addition, replacement or ignore of those discovered
hosts by the failover transport and provide an event point for
connection listeners to see the discovered resources.

> A server might be able to provide a list of known alternates that a client can connect to should that server go down. By supporting a connection property in the Open frame we can read and update or replace the failover URIs for the client based on the server provided information.
> The client will look for a connection property in the Open frame named "failover-server-list" whose value is a list. Each element in the list would be a Map, with the entries in the map providing the connection details. The connection details would be of the same form as specified for [connection redirect|http://docs.oasis-open.org/amqp/core/v1.0/os/amqp-core-transport-v1.0-os.html#choice-connection-error-redirect], optionally with the extensions for websocket connections defined [here|http://docs.oasis-open.org/amqp-bindmap/amqp-wsb/v1.0/cs01/amqp-wsb-v1.0-cs01.html#_Toc461801619] (the notion of scheme introduced here may be generally useful to distinguish between TLS and non-TLS connections).
