Renaming the install and uninstall normative workflows

[Steve Baillargeon]

Hi
The YAML Profile 1.1 has officially named the normative workflows to be:
*             deploy: is the workflow used to instantiate and perform the 
initial deployment of the topology.
*             undeploy: is the workflow used to remove all instances of a 
topology.
I suggest we rename the current install/uninstall workflows in ARIA with the 
new names.
What do you think?
Regards
