AWS policy management package

[leeper]

Most policy-related API functions overwrite/replace existing policies. This is fine but fairly annoying if you just want to change a policy. We need a package that can:

• Parse policies into an R representation (basically just jsonlite::fromJSON() with some non-default options)
• Construct policies in a consistent way (basically just jsonlite::toJSON() with some non-default options)
• Policy modification functionality (maybe R6 style?)
