Support Sending Messages Alongside Frame Data

This change support sending messages with records. The tuple Appender
reserves 100 bytes for a message. Before sending the frame, it appends
The message in the last tuple position. The message is read from the
task context as the shared object between different operators in the
pipeline. The first use of this feature will be within feeds to request
acks for at least once semantics.
