request types for type-safe requests

[mfulton26]

Is your feature request related to a problem? Please describe the problem.

I want to make my request payloads properly with code completion and type checking but from what I can tell there is only types for response payloads but not request payloads.

Describe the solution you'd like.

Types for request payloads to compliment the response payload types.

Additional context?

e.g. I can use MeetingTimeSuggestionsResult but there's no FindMeetingTimes type to help in constructing/type-checking the request payload.
