### Description
This adds a new diagnostics event `http_request_performed` with some
useful information we would like to track about the http requests
performed to our servers.
This will be logged when doing so:
```
ERROR: 😿❗❗ Error computing offline CustomerInfo. Will return original error.
Creation error: Unable to compute offline CustomerInfo when purchasing consumable products.
```
### Changes:
- Added unit tests for `PostReceiptDataOperation`
- Added integration test for this new scenario
- `PostReceiptDataOperation` won't use `OfflineCustomerInfoCreator` when
purchasing consumable products
### Changes:
- Created `PurchasedProductsFetcherType` to be able to mock and hold
fetchers, even on older devices
- Created `ProductEntitlementMappingFetcher` to abstract injecting
`ProductEntitlementMapping`
- Added logic to `CustomerInfoResponseHandler` to compute offline
`CustomerInfo` after a server error (see #2367). **This is used by all
`CustomerInfo` requests as well as `PostReceiptDataOperation`**.
- Wrote comprehensive `CustomerInfoResponseHandler` tests
### TODO:
- [x] Don't cache offline computed `CustomerInfo`: #2378
- [x] Integration tests: #2501.
### Changes:
- Added `Purchases.configureInCustomEntitlementsComputationMode`
- Added `Purchases.switchUser(to:)`
- Disabled parts of the SDK in this new mode
- New example app for testing `customEntitlementsComputation` mode

See also #2397.
Xcode 14.3 introduced the following error:
> Heterogeneous collection literal could only be inferred to '[String :
Any]'; add explicit type annotation if this is intentional
### Changes:
- Added explicit types to fix this new error
- Removed unnecessary `@preconcurrency` imports
- Added new `CustomerInfo.emptyInfo` to reduce duplication of same fake
`CustomerInfo` creation
Essentially we don't want to modify any behavior on `.informational`
mode. Everything will continue behaving normally, and simply report
verification failures.
Instead of manually choosing when to include `nonce` in requests, this
data-driven approach ensures that all requests to endpoints that support
signature verification will make `HTTPClient` do the right thing.
See also #2277 for how `CustomerInfo` and `EntitlementInfo` will use
this.
* Create and plumb MockIdentityAPI
* MockOfferingsAPI and remove proxied OfferingsAPI api from Backend
* Reference identity directly, instead of backend.identity
Extract out various dependencies that are required to instantiate the `Backend` object.
Refactor to assist with the next few PRs that extract out other pieces
See [CSDK-82]
Resolves [CSDK-155]
* Resolves [CF-443]
* Adds `configureWithConfiguration` to `RCPurchasesAPI.m`
* Create Configuration object and API to configure Purchases
* Update API doc for new Purchases API
* Add example code to Configuration documentation
* Adds deprecations for various Purchases.configure methods
## Motivation:
There is no way to run code statically like in Obj-C using `+ [NSObject initialize]`, so this ensures (through a new `SwiftLint` rule) that all test classes inherit this common test class instead of `XCTestCase` directly.
A future PR will make use of this new `CIRCLECI_TESTS_GENERATE_SNAPSHOTS` environment variable to allow regenerating snapshots in CI.
I've also moved the duplicated `CurrentTestCaseTracker` usages to a single point.
* moved test suites to Tests folder
* fixed outdated path
* fixed more outdated paths
* moved TestsPlans to Tests folder
* update path to Constants.swift
