TCP port does not guarantee that all data is written

[konnorandrews]

Bug report

The TCP port can lose data.

Context

Utils/cpp/Comm::TCP::Port

Expected result

A call to push(buffer, length) is expected to completely send all the data in the buffer to the length provided.

Current result

Calls can result in only a partial amount of data being sent.

Possible Fix

Use the return sizes from write(...) to continue to send data.
