NachoSoto da9ba397a3 Update CustomerInfo.requestDate from 304 responses (#2310)
### Purpose:

This is a prerequisite for #2288. The new grace period means that if we
didn't update the date from the cached responses, entitlements would
become stale and expired after 3 days.

### Changes:
- Added `HTTPResponseBody.copy(with newRequestDate:)` to be able to
modify responses from the header request date
- `CustomerInfo` implements this method to modify its request date
- Added `HTTPResponse.requestDate` to be able to keep track of the
request date from the server
- Added `VerificationResult.from(cache:response:)` to determine the most
restrictive verification result based on what's cached or checked from a
response
- Added `HTTPResponse.copy(with:)` to modify the verification result of
a response using the previous method
- `HTTPClient` now uses the most restrictive verification result
- `HTTPClient` updates request date from server responses or cached
responses (unless verification failed). This was the missing piece for
#2288.

### Tests:
- Verify that `ETagManager` does not use an ETag if verification was
previously not enabled
- Verify that `ETagManager` returns the request date from the server
when returning a cached response
- Verify that `HTTPClient` updates the request date from the server or
from a cached response
- Verify that `HTTPClient` does not update request date if verification
failed
- Tests for `HTTPResponse` request date parsing
- Test for `CustomerInfoResponseHandler` updating request date
- Tests for `CustomerInfo.copy(with newRequestDate:)`


### Other smaller changes:
- Moved `CustomerInfo.asData()` into `Encodable.asJSONEncodedData()`
- Renamed `requestTime` to `requestDate` everywhere for consistency
