For pyamqp, if connection url contains amqps, then certificates are never validated against provided ca certificates

For pyamqp transport, if connection url contains the string amqps(notice the s), then the server certificates are never validated against the ca certs, even if they are provided.
Inside pyamqp.py. file line 182

`class SSLTransport(Transport):
"""AMQP SSL Transport."""

def __init__(self, *args, **kwargs):
    super(SSLTransport, self).__init__(*args, **kwargs)

    # ugh, not exactly pure, but hey, it's python.
    self.client.ssl = True`

The above code demonstrates the part where they are overwritten.

Creating the custom connection object

connection = kombu.Connection(
"amqps://guest:guest@localhost:5671",
login_method="PLAIN",
ssl={
'ca_certs': '"ca_cert_path",
'cert_reqs': ssl.CERT_REQUIRED
}
)

But if the url contains the string amqp(without s), then the server certificates are validated.
