Use get_required to raise RequiredPropertyMissing when appropriate

[duckontheweb]

Related Issue(s):

• Closes Implement RequiredPropertyMissing exception where appropriate #315

Description:

Updates codebase to use utils.get_required instead of raising RequiredPropertyMissing directly. Also updates usages to always use .get(some_prop) instead of [some_prop] to ensure we get RequiredPropertyMissing instead of KeyError.

Reviewed the extensions, looks like all non-optional getter properties are now using get_required 👍
