docs: request a connection close
  
          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.
