Improved package init and publish flow

[calvinrp]

When publishing either a package Release or Init, a new error ConflictPendingPublish(RecordId) may be returned.

This instructs the client that it could wait for the conflicting pending record (on the same LogId package) to complete and then retry to publish.

If a registry service offers key management and needs to sign the Init record, this enables a smoother experience and messaging on the CLI. Where the registry would return the RecordId of the registry signed Init record as a ConflictPendingPublish error, the CLI would wait for that record to publish and then retry. Since the package is already initialized, an error message would be presented that indicates that the package was initialized but not with the Init record that you signed.

Also, added a feature flag for cli-interactive for the warg-client and a config flag to disable dialoguer interactive prompting even when that feature is enabled.

Negative feature comment is only blocker

Also, added a output option for the warg download -o subcommand. And, if output arg is omitted`, asks the user if wants to have the file written to the CWD. Otherwise, just downloads to the local cache which is kind of confusing and hard to find the file.

Sorry I completely missed these changes in my first pass: "Large diffs are not rendered by default." 🙄
