Tests: add propagate_connection_close tests.

propagate_connection_close causes nginx to close the downstream connection if
the upstream returns a "Connection: close" header.

This change adds tests for the existing/default behavior as well as enabled and
disabled. For each setting, it does two tests: one that will cause the upstream
server to close the connection and one that will cause the upstream server to
keep the connection alive.
