        open connection to virtual host

        This method opens a connection to a virtual host, which is a
        collection of resources, and acts to separate multiple
        application domains within a server.

        RULE:

            The client MUST open the context before doing any work on
            the connection.

        PARAMETERS:
            virtual_host: shortstr

                virtual host name

                The name of the virtual host to work with.

                RULE:

                    If the server supports multiple virtual hosts, it
                    MUST enforce a full separation of exchanges,
                    queues, and all associated entities per virtual
                    host. An application, connected to a specific
                    virtual host, MUST NOT be able to access resources
                    of another virtual host.

                RULE:

                    The server SHOULD verify that the client has
                    permission to access the specified virtual host.

                RULE:

                    The server MAY configure arbitrary limits per
                    virtual host, such as the number of each type of
                    entity that may be used, per connection and/or in
                    total.

            capabilities: shortstr

                required capabilities

                The client may specify a number of capability names,
                delimited by spaces.  The server can use this string
                to how to process the client's connection request.

            insist: boolean

                insist on connecting to server

                In a configuration with multiple load-sharing servers,
                the server may respond to a Connection.Open method
                with a Connection.Redirect. The insist option tells
                the server that the client is insisting on a
                connection to the specified server.

                RULE:

                    When the client uses the insist option, the server
                    SHOULD accept the client connection unless it is
                    technically unable to do so.
