default isLegacyGetEnabled to false for Data and Cache api #550
Description
Related to #531 , this flag is currently defaulted to true. We eventually will need to update this flag to default to false, in prep for eventually removing the flag.
This should be a major release of hyper core
As a hyper developer
I would like hyper data service and hyper cache service "get" apis to return a hyper response shape, default
So that consumers can start to receive the hyper response shape that will be used, going forward
Scenarios
Default to hyper response shape
GIVEN I am a developer
AND I am calling the Data Service "get document" or Cache Service "get value" api
WHEN I do NOT provide the `isLegacyGetEnabled` flag, ie. set `X-HYPER-LEGACY-GET` header
THEN I will receive the hyper response shape
Opt-in to legacy shape
GIVEN I am a developer
AND I am calling the Data Service "get document" or Cache Service "get value" api
WHEN I DO provide the `isLegacyGetEnabled` flag, ie. set `X-HYPER-LEGACY-GET` header
THEN I will receive the legacy shape (the document or value directly)
