commcare: Create a generic request function

[hunterachieng]

Background, context, and business value

Create a generic request function in the commcare adaptor

The specific request, in as few words as possible

We currently do not have a common request function which would allow us to implement more features api calls using commcare

@hunterachieng as discussed, please implement this in the adaptor so we can send generic GET/POST/PUT requests. This will be good to generally implement, as well as unblock us on HIH.

We have created 2 functions, request for normal json body requests and bulk for both submitxls and lookup-table updates

hey @hunterachieng can we close this out?
