password AMQP URI parameter is parsed incorrectly

[lukebakken]

Describe the bug

In my testing, I found that the query parameter &password=xxx overrides the password in "amqps://user:pass@rabbitmq-host:5671", i.e. in this link it will use user:xxx to log into RabbitMQ instead of user:pass:

amqps://user:pass@rabbitmq-host:5671?cacertfile=/etc/rabbitmq/ssl/ca_certificate.pem&certfile=/etc/rabbitmq/ssl/client_certificate.pem&keyfile=/etc/rabbitmq/ssl/client_key.pem&verify=verify_peer&password=xxx

Reproduction steps

To see how this is parsed, start up RabbitMQ with RABBITMQ_ALLOW_INPUT=true and enter the following into the Erlang shell:

(rabbit@shostakovich)3> amqp_uri:parse(<<"amqps://user:pass@rabbitmq-host:5671?cacertfile=/etc/rabbitmq/ssl/ca_certificate.pem&certfile=/etc/rabbitmq/ssl/client_certificate.pem&keyfile=/etc/rabbitmq/ssl/client_key.pem&verify=verify_peer&password=xxx">>).

{ok,{amqp_params_network,<<"user">>,"xxx",<<"/">>,
                         "rabbitmq-host",5671,2047,0,10,60000,
                         [{server_name_indication,"rabbitmq-host"},
                          {password,"xxx"},
                          {verify,verify_peer},
                          {keyfile,"/etc/rabbitmq/ssl/client_key.pem"},
                          {certfile,"/etc/rabbitmq/ssl/client_certificate.pem"},
                          {cacertfile,"/etc/rabbitmq/ssl/ca_certificate.pem"}],
                         [#Fun<amqp_uri.9.95926583>,#Fun<amqp_uri.9.95926583>],
                         [],[]}}

Note that xxx is the AMQP login password as well, whoops.

Expected behavior

The AMQP password is not overridden.
