Build remote-test-server copy to image and execute
remotely through background ssh.

Execute rust testing by exporting required paths. Capturing
test results in summary.txt at rust source folder.

We are booting qemuimage in "nographic" mode along with additional
qemuparams,
'-monitor telnet:127.0.0.1:1234,server,nowait -serial mon:stdio -serial null'

Note:
'-serial mon:stdio -serial': To fix below run-time errors while testing
"failed with Connection reset by peer"
