ZhenhuaZhang 496ed99cea declear roles as roles_array internally when installing on ubuntu
There are actually two `roles` setting in ubuntu installation scripts.
One is roles as string, which can be set as env and then used in scripts.
The other is roles as array, which is used by internal handling to
locate specific role by offset.

This patch tries to distinguish roles meaning by declearing the second
as roles_array, thus eliminating its ambiguity.
