Add an exec to create the Deploy Environments RBAC Role
Add an exec to create the Deploy Environments RBAC Role

Prior to this commit there was a requirement for the user of this
repo to create a RBAC role in order for code manager to work.

After this commit an exec statement will curl the RBAC API to
create the role one time and hopefully it works otherwise the exec
will not run again.
