Log raw requests and responses when running availability check with debug flag

[girarda]

What

The debug flag is used to log raw requests sent to an API source.

The requests sent as part of the stream availability check are not logged because we only apply the Source's log level to the Stream after the availability check.

Proposed solution

Apply the log level to the stream logger before we check if the stream is available (before line 116)

Acceptance criteria

• Requests and responses from the availability check are logged when running with the debug flag
• The connector builder either ignores these requests or shows them as auxiliary requests

grooming notes:

• need to make sure the requests will actually be output by SimpleRetrieverTestReadDecorator
• The requests and responses should show up in the connector builder as auxiliary requests
