Why GET /ehr/{ehrId}/versioned_ehr_status returns only revision_history?

[ppazos]

Shouldn't be more RESTful to have a dimension per each method in VERSIONED_OBJECT? And leave GET /ehr/{ehrId}/versioned_ehr_status to return just uid, owner_id and time_created.

GET /ehr/{ehrId}/versioned_ehr_status/revision_history
GET /ehr/{ehrId}/versioned_ehr_status/all_versions
GET /ehr/{ehrId}/versioned_ehr_status/latest_trunk_version
GET /ehr/{ehrId}/versioned_ehr_status/version_at_time
etc.
