What's changed

This PR includes a couple of updates to how the resultant headers were computed for Digest Authorization, ensuring the request is transmitted in the expected format:

• Only include the path and query parameters in the URI.
• Account for the opted algorithm (additional implementation for MD5-sess) while hashing username, realm and password.
• Include an entity (request) body hash when qop is set to auth-init. For content types like multipart/form-data where the request body is not a string, it falls back to an empty string while hashing for now.

Additionally, it includes the following changes:

• Account for the www-authenticate header received from the server in the initial response in a case-insensitive manner. Previously, if the server responded with the WWW-Authenticate header, the initial response would be marked with an unexpected response since www-authenticate was referred to straightaway.
• Removes the Disable Retrying Requests for the time being until a mechanism is in place to handle failed requests gracefully in such a case. CLI will still support this.
• The CLI behaviour has been updated so that any failures reported in the pre/post scripts and request execution will result in a non-zero exit code. Previously, this behaviour was exclusive to failed test assertions.
• CLI test suite updates.

Notes to reviewers

Ensure the request succeeds every time. Also, export the collection and run it via the CLI. Specify disableRetry: true in the exported collection under auth for the request and observe the request failing with a suitable message.
