xci: Add ability to pass command line options to xci-deploy.sh

We now support multiple PDF files so instead of introducing another
env variable, we can simply pass this information as command line
arguments to xci-deploy.sh. We can extend the script to allow more
options line verbosity, scenario name, functest details etc so we
can get rid of multiple env variables.
