1. Add ArrayEncodedMap …

   It's a common pattern in Porter to represent a map of items, with a unique key, as a list in the porter.yaml or a file representation of the resource because the UX for autocomplete is better. We can't change that now, parameters and credentials for example will always be a list, but we can use a map in Porter's code so that it's easier to work with.
   
   I've added ArrayEncodedMap, a data structure that reads in a list and stores it in-memory as a map:
   
   - name: a
     value: stuff
   - name: b
     value: things
   
   We can use this as a base data structure initially for Parameter and Credential Sets, storing the mapping of the parameter/credential name to the secret resolution strategy. Over time, it may make sense to use it for the other data structures in porter.yaml as well.
   
   It has support for iterating as a map, or as a sorted list of values. The sorted list is good for unit tests, and anytime we need the output to be stable. The map isn't exposed directly and I have a funky "best you can do with Go" iterator to help keep our for loops looking pretty normal.
