Description

Support more character types in stack names.

Cfn stacks are currently limited to 128 alphanumeric and dash characters. We'd like it expanded to include periods and other symbols.

Matching what's allowed for IAM role names would be preferred (alphanumerics and _+=,.@-).

Other Details

We'd like to be able to have a human-friendly "fully-qualified" name for all AWS resources. For example, suppose a service is organized hierarchically by:

1. Stage
2. Region
3. Cell

We'd like to name a stack my-service.us-east-1.cell-0.my-stack, where period is used as the separator between level fragments.

Using fully qualified names lets us deploy multiple copies of a service into the same account during development (e.g. have cell 0 and cell 1 in the same personal development account).

Currently we have to use something like -- as the separator which can be difficult to read. For example, my-service--us-east-1--cell-0--my-stack.
