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.
Motivation
Allowing arbitrary data in outbound header field values allows for the
possibility that users of AHC will accidentally pass untrusted data into
those values. That untrusted data can substantially alter the parsing
and content of the HTTP requests, which is extremely dangerous. The
result of this is vulnerability to CRLF injection.
Modifications
Add validation of outbound header field values.
Result
No longer vulnerable to CRLF injection
### 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.
- Refactored code from `TaskHandler` into new method `HTTPClient.Request.createRequestHead` that creates an `HTTPRequestHead` and matching `RequestFramingMetadata`
- Added required property `requestFramingMetadata` to `HTTPExecutingRequest`
- Added property `requestFramingMetadata` to `RequestBag`

- Adding four new protocols:
- `HTTPExecutingRequest` a protocol representing an HTTP task that is executed on a ChannelHandler.
- `HTTPScheduledRequest` a protocol representing an HTTP task that is scheduled for execution, but in a waiting state (example: Waiting for an idle connection in the connection pool).
- `HTTPRequestExecutor` a protocol that can be used from the `HTTPExecutingRequest` abstracting away functionality that will normally be implemented by a `ChannelHandler`
- `HTTPRequestScheduler` a protocol that can be used from the `HTTPScheduledRequest` abstracting away functionality that will normally be implemented by a `ConnectionPool`
- An implementation of the `HTTPExecutingTask` and `HTTPScheduledRequest` called `RequestBag`. It implements our current API using the new protocols

Motivation:
Streams length parameter is optional to allow cases were stream length is not known in advance, but we do not support this in request validation. This PR aims to address that.
Modifications:
Modifies request validation to default to chunked encoding if body length is zero or to passed in content-length header
Adds a test
Result:
Closes#218
motivation: the Swift Server Workgroup is not a legal entity and cannot hold copyrights. with this change, code authors continue and retain their copyrights under the apache license and previous copyrights note, but Apple steps up instead of the workgroup which has no legal status
changes:
* update header files to say "Apple Inc. and the AsyncHTTPClient project authors" instead of "Swift Server Workgroup and the AsyncHTTPClient project authors"
* update validation scripts to check for the correct header
* add CONTRIBUTING.md file to explain how to make contributions and include a legal notice about licensing the contribution to Apple and the project
* regenerate CONTRIBUTORS.md to reflect most recent contributions
