Blueprint Framework - Implement behaviour to derive a chain of links from a loaded blueprint

[fr3shw3b]

Implement SpecLinkInfo interface and default implementation that produces a "ChainLink" from a blueprint that has been loaded. This should identify circular dependencies, producing errors and warnings when hard cycles are identified.

There are two types of links for resources.

Hard links - These are links that in which the priority resource type is a hard dependency for the other resource in the relationship. (e.g. Infrastructure-level link from DynamoDB Table to DynamoDB Stream)

Soft links - These are links in which the priority resource type is not a hard dependency for the other resource in the relationship. (e.g. Application-level link from Lambda to DynamoDB)

The implementation of transforming a blueprint into a chain of links needs to take this into account. The hard link and soft link distinction must be well documented!

Need to document the distinction between hard and soft links! (Celerity docs site and in accompanying documentation in the repo)
