Implement AWS "Updates are not supported" feature

Registered by Pavlo Shchelokovskyy

As Heat tries to maintain compatibility of its AWS resources, a user can expect that a template using Heat's AWS compatible resources will work the same both on Heat and on AWS. Currently though we are missing a specific behavior of some AWS resources on stack update - a property of resource might not support any updates, including UpdateReplace (that is currently our default update behavior).
