Dumping a `ReflectionAttribute` just yields `ReflectionAttribute {#4711}` which is not really helpful. This PR attempts to fix this.```ReflectionAttribute {#4711  name: "App\MyAttribute"  arguments: array:2 [    0 => "one"    "extra" => "hello"  ]}```While working on this, I noticed that class constants (which can be reflected on since PHP 7.1) are just dumped as plain values, so I've also added a caster for `ReflectionClasConstant` as bonus.The full output for the `LotsOfAttributes` fixture class that is included with is PR looks like this:<details>```^ ReflectionClass {#7  +name: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"  modifiers: "final"  implements: []  constants: array:1 [    0 => ReflectionClassConstant {#20      +name: "SOME_CONSTANT"      +class: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"      modifiers: "public"      value: "some value"      attributes: array:2 [        0 => ReflectionAttribute {#33          name: "Symfony\Component\VarDumper\Tests\Fixtures\RepeatableAttribute"          arguments: array:1 [            0 => "one"          ]        }        1 => ReflectionAttribute {#34          name: "Symfony\Component\VarDumper\Tests\Fixtures\RepeatableAttribute"          arguments: array:1 [            0 => "two"          ]        }      ]    }  ]  properties: array:1 [    "someProperty" => ReflectionProperty {#19      +name: "someProperty"      +class: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"      modifiers: "private"      attributes: array:1 [        0 => ReflectionAttribute {#30          name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"          arguments: array:2 [            0 => "one"            "extra" => "hello"          ]        }      ]    }  ]  methods: array:1 [    "someMethod" => ReflectionMethod {#21      +name: "someMethod"      +class: "Symfony\Component\VarDumper\Tests\Fixtures\LotsOfAttributes"      returnType: "void"      parameters: {        $someParameter: ReflectionParameter {#28          +name: "someParameter"          position: 0          attributes: array:1 [            0 => ReflectionAttribute {#42              name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"              arguments: array:1 [                0 => "three"              ]            }          ]          typeHint: "string"        }      }      attributes: array:1 [        0 => ReflectionAttribute {#27          name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"          arguments: array:1 [            0 => "two"          ]        }      ]      modifiers: "public"    }  ]  attributes: array:1 [    0 => ReflectionAttribute {#22      name: "Symfony\Component\VarDumper\Tests\Fixtures\MyAttribute"      arguments: []    }  ]  extra: {    file: "./src/Symfony/Component/VarDumper/Tests/Fixtures/LotsOfAttributes.php"    line: "15 to 28"    isUserDefined: true  }}```</details>Commits-------34dbf01 [VarDumper] Support for ReflectionAttribute.

…lishing a message.

another queue, you can encounter `AMQPConnectionException` with the message "Library error: a SSL error occurred" or "a socket error occurred"  depending on if you are using tls or not or if you are running behind a load balancer or not.You can manually reproduce this issue by dispatching a message where the handler then dispatches another message to a different queue, then go to rabbitmq admin and close the connection manually, then dispatch another message and when the message handler goes to dispatch the other message, you will get this exception:```a socket error occurred#0
