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.
* Introduce helper methods for test of ConnectionsState
Motivation:
Issue #234 highlights that we directly manipulate ConnectionsState and
this commit prepares tests to be refactored to manipulate the state
by exposed APIs instead.
Modifications:
* introduce helper methods in ConnectionPoolTestsSupport.swift
Result:
* no observable changes
* Move Connection tests out of ConnectionsState tests into separate file.
Motivation:
Clean up of code to address issue #234 - here we move away
connection tests to separate files outside of ConnectionsState tests
so we will be able to work on the ConnectionsState in focussed mode.
Modifications:
Connection tests moved to separate files.
Result:
No observable changes.
* Gather Connection code into Connection.swift
Motivation:
For tests we will need a simple version of Connection, so here I gather
Connection code in one place and will generify ConnectionsState on next
commit.
Modifications:
Code of Connection is moved from multiple files into single
Connections.swift.
Result:
All tests are passing, no observable behaviour change.
* Introduce generic type ConnectionType into ConnectionsState
Motivation:
To rework tests of ConnectionsState we want to have a "simpler" version
of Connection to be used, therefore here we convert ConnectionsState to
support generic type ConnectionType. We will substitute current
Connection with a test version in follow up commit.
Modifications:
ConnectionsState is altered to work on generic type ConnectionType
instead of solid type Connection.
Users of ConnectionsState are modified to provide type Connection into
ConnectionType in this commit.
Result:
Test are passing, no observable behaviour change.
Motivation:
AsyncHTTPClient is not a simple piece of software and nowadays also
quite stateful. To debug issues, the user may want logging.
Modification:
Support passing a logger to the request methods.
Result:
Debugging simplified.
