feat: add --retries / PACT_BROKER_HTTP_RETRIES to pact_verifier_cli

[JP-Ellis]

Exposes broker HTTP retry count as --retries (env: PACT_BROKER_HTTP_RETRIES,
default: 8) in pact_verifier_cli, matching the flag in pact-broker-cli.

The retry count is threaded through VerificationOptions.broker_request_retries into the HALClient used for all broker calls: pact fetching (both legacy and dynamic) and publishing verification results.

pact_verifier and cli bumped to 1.4.0

pact_verifier and cli bumped to 1.4.0

Such a tiny change for a version bump?

[JP-Ellis]

The main thing here is a new flag, hence the new minor version.

Technically, there's a breaking change (the typo fix is part of the public interface...).

Up to you what version bump you prefer. I can fix up this PR easily.

[rholshausen]

Ok, I've reset the version on the CLI but kept the version bump for the verifier crate.

There is a failing test, as the error text has now changed:

Couldn't be bothered dealing with the merge commit when I rebased... so it clobbered the git history. Anyway, error is fixed, kept the minor version bump for the pact_verifier breaking change, and reverted the version bump for the pact_verifier_cli.
