Send terminal erase sequence on tripleo deploy

Browse Source 
We're seeing some escape sequences being dropped when we run the
deployment via the undercloud. This causes a user to have to run a reset
after the undercloud installation in order to be able to use their shell
command line again.  We can avoid this if we send an terminal erase line
sequence to trim the rest of the line at the end of the deploy.
