Change logic around closing connections and writers API-1283

[srknzl]

fixes #1256

The issue was writing some data to the connection after it being closed. I changed and refactored some logic around PipelinedWriter and Connection to avoid that.

• Moved socket closing responsibility to Writers
• Fixed a test in PipelinedWriterTest
• Ongoing and future socket.write calls will end with an error after the writer is closed. This is because close() destroys the socket and any ongoing and future socket.write calls will end with an error as described in node.js documentation. So we will be able to reject all deferred promises in the write queue upon close due to connection.close() or socket write error close().
• We were not closing the socket on write error before, now we do it. We were sending end packet and don't write anymore. This is the same as java. See

Note regarding coverage: The coverage drop is shown as 0.16% but I see that the drop is due to SSL tests because the drop is in connectTLSSocket. I think it should be related to the ssl tests being disabled. (Due to certificate issue)

Also note that codecov does not show a line that is added but not covered in this PR. (except a single line, I explained it above)
