Migrate CI to use GitHub Actions.
### Motivation:
To migrate to GitHub actions and centralised infrastructure.
### Modifications:
Changes of note:
* Adopt swift-format using rules from SwiftNIO.
* Remove scripts and docker files which are no longer needed.
* Disabled warnings-as-errors on Swift 6.0 CI pipelines for now.
### Result:
Feature parity with old CI.
Since most of the servers now conform to http2, the change here updates
the behaviour of assuming the connection to be http2 and not http1 by
default. It will migrate to http1 if the server only supports http1.
One can set the `httpVersion` in `ClientConfiguration` to `.http1Only`
which will start with http1 instead of http2.
Additional Changes:
- Fixed an off by one error in the maximum additional general purpose
connection check
- Updated tests

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.
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.
