When using the json output of the cli (`-format=json`), a successful
call to the controller API would place the HTTP status code in the JSON
as `status_code`. However, if there was an error from the API the status
code would be placed in the JSON as `status`. In order to be consistent,
this adds a `status_code` field to the error response case. For
backwards compatibility it still populates `status` in the error case.
This inconsistency was missed partially due to a bug in the CLI tests.
The assertion on status code was not valid and would always be
successful. Thus this also fixes the assertions and tests.
* Sessions support for read:self and cancel:self permissions. This is automatic with fallback; no API change is needed.
* Strips out values from listing if only self actions are allowed on the resource and the user ID is different. This prevents a default ACL of id=*;type=session;actions=read:self,cancel:self from causing all values to be visible when listing.
* Adds an unprivileged user to development/testing instances. This user has only default permissions plus the ability to authorize sessions in the default target.
