Since amqp 2.0 you have to explicitly call Connection.connect()
before using the connection.

The connection class provides methods for a client to establish a
network connection to a server, and for both peers to operate the
connection thereafter.
GRAMMAR::
connection = open-connection *use-connection close-connection
open-connection = C:protocol-header
S:START C:START-OK
*challenge
S:TUNE C:TUNE-OK
C:OPEN S:OPEN-OK
challenge = S:SECURE C:SECURE-OK
use-connection = *channel
close-connection = C:CLOSE S:CLOSE-OK
/ S:CLOSE C:CLOSE-OK
Create a connection to the specified host, which should be
a 'host[:port]', such as 'localhost', or '1.2.3.4:5672'
(defaults to 'localhost', if a port is not specified then
5672 is used)
Authentication can be controlled by passing one or more
`amqp.sasl.SASL` instances as the `authentication` parameter, or
setting the `login_method` string to one of the supported methods:
'GSSAPI', 'EXTERNAL', 'AMQPLAIN', or 'PLAIN'.
Otherwise authentication will be performed using any supported method
preferred by the server. Userid and passwords apply to AMQPLAIN and
PLAIN authentication, whereas on GSSAPI only userid will be used as the
client name. For EXTERNAL authentication both userid and password are
ignored.
The 'ssl' parameter may be simply True/False, or
a dictionary of options to pass to :class:`ssl.SSLContext` such as
requiring certain certificates. For details, refer ``ssl`` parameter of
:class:`~amqp.transport.SSLTransport`.
The "socket_settings" parameter is a dictionary defining tcp
settings which will be applied as socket options.
When "confirm_publish" is set to True, the channel is put to
confirm mode. In this mode, each published message is
confirmed using Publisher confirms RabbitMQ extension.

This method indicates that the sender wants to close the
connection. This may be due to internal conditions (e.g. a
forced shut-down) or due to an error handling a specific
method, i.e. an exception. When a close is due to an
exception, the sender provides the class and method id of the
method which caused the exception.
RULE:
After sending this method any received method except the
Close-OK method MUST be discarded.
RULE:
The peer sending this method MAY use a counter or timeout
to detect failure of the other peer to respond correctly
with the Close-OK method.
RULE:
When a server receives the Close method from a client it
MUST delete all server-side resources associated with the
client's context. A client CANNOT reconnect to a context
after sending or receiving a Close method.
PARAMETERS:
reply_code: short
The reply code. The AMQ reply codes are defined in AMQ
RFC 011.
reply_text: shortstr
The localised reply text. This text can be logged as an
aid to resolving issues.
class_id: short
failing method class
When the close is provoked by a method exception, this
is the class of the method.
method_id: short
failing method ID
When the close is provoked by a method exception, this
is the ID of the method.
