### Motivation
Our current swiftformat version does not support async/await. Since we want to add support for async/await we must update swiftformat or disable it. I tried my very best to keep the number of changes as small as possible. I assume we want to stick with the new 0.48.8 for some time.
### Changes
- Update swiftformat to 0.48.8
### Result
We can land async/await code.
### Motivation
Generally we want to inform users that they need to shutdown their HTTPClient. Until `1.6.0` we did this with an assert in HTTPClient's deinit. With `1.6.0` this behavior was raised to a precondition. Because of this adopters might suddenly crash in production where they didn't before.
### Changes
- This pr reverts the current behavior back to something pre `1.6.0`
### Result
- HTTPClient doesn't crash in production anymore.
### Motivation
Fixes#238 and #231.
### Changes
- Extracted the unclean shutdown test from `HTTPClientTests` into their own file `HTTPClientUncleanSSLConnectionShutdownTests`
- Copy and pasted @weissi great explanation from #238 into the test file
- Removed property `ignoreUncleanSSLShutdown` everywhere
### Result
`ignoreUncleanSSLShutdown` on `HTTPClient.Configuration` is deprecated and ignored.

Motivation:
In according to RFC 6265 a cookie value may be placed between double quotes.
Modifications:
HTTPClient.Cookie ignores now the double quotes at the beginning and the ending of a cookie value.
New unit test is added to check it.
Result:
Quoted cookie values are parsed properly now.
Motivation:
If we backoff sufficiently far we can overflow Int64, which will cause
us to crash.
Modifications:
Clamp the backoff value before we convert to Int64.
Results:
No crashes!
- `_idleTimer` and `_backoffTimer` are protected by `stateLock`
- Added a new `struct Actions` that splits up actions from the state machine into actions that need to be executed inside the `stateLock` and outside in `stateLock`
- Add HTTP/1.1 connection pool stress test
- a new `RequestOptions` struct was created, that can be used to set request specific options. It is required by the `HTTPExecutableRequest`
- Added support for `ignoreUncleanSSLShutdown` in the `HTTPRequestStateMachine` and the `HTTP1ConnectionStateMachine`. In http/2 `ignoreUncleanSSLShutdown` is always off.
### Motivation
NIO may send `channelRead` events without a handlers requesting more data with a `context.read()` invocation. This happens if the remote has closed the connection and NIO wants to inform the handlers as soon as possible.
### Changes
- Don't `precondition` on `channelRead` events anymore.
- Close channel if we received an http end without a `context.read()` invocation
### Motivation
In the `HTTP1ConnectionStateMachine` we set the connection state to `.closed` after having forwarded an error to the inner RequestStateMachine. Since we set the state to close, the `state.modify` function did not create an action that would close the connection.
### Changes
- Modify the ConnectionState based on the RequestStateMachine's action only in the `state.modify` function.
- Add a test to verify the fixed behavior.
- Use ExpressibleByDictionaryLiteral syntax for some HTTPHeaders to increase readability.
### Result
Connections are closed, if an error happens, while we are in a request.
If a request times out because no connection could be attained, we should fail the request with the last connection creation error. If no connection creation error is present and there is no active connection, we fail the request with a connectTimeout error.
