commit 5b95bb0f21852058d22703385f2c8e139881bf1a

Fixed HTTP errors caused by dropped HTTP responses by IOSwitchboard.
Previously, IOSwitchboard process could terminate before all HTTP
responses had been sent to the agent. In the case of
`ATTACH_CONTAINER_INPUT` call, we could drop a final HTTP `200 OK`
response, so the agent got broken HTTP connection for the call.
This patch introduces an acknowledgment for the received response
for the `ATTACH_CONTAINER_INPUT` call. This acknowledgment is a new
type of control messages for the `ATTACH_CONTAINER_INPUT` call. When
IOSwitchboard receives an acknowledgment, and io redirects are
finished, it terminates itself. That guarantees that the agent always
receives a response for the `ATTACH_CONTAINER_INPUT` call.
