* Add new 'pulumi state' command for editing state This commit adds 'pulumi state unprotect' and 'pulumi state delete', two commands that can be used to unprotect and delete resources from a stack's state, respectively. * Simplify LocateResource * CR: Print yellow 'warning' before editing state * Lots of CR feedback * CR: Only delete protected resources when asked with --force
