Current user parameter default is automation and this is defined at the outer (parser) level meaning that it is visible in the help text and reference documentation as the default. While this was helpful and still appropriate for Server, it is not valid for Cloud (Jira and Confluence) as Cloud now requires an email address for the user parameter.
Therefore we are making the following changes:
Remove default value so that it will no longer appear in help text and reference documentation
We will still default Server to automation to maintain compatibility so there is no impact to existing usage
We will default Cloud to anonymous which will make it easy to access sites that support anonymous access. This still maintains compatibility in the sense that Cloud users were required to provide a user parameter anyway to avoid an error based on the automation user now being invalid on Cloud.
This change also covers the Bitbucket Cloud client.
