Update room configuration

Room outline as ordered list of vertices of a simple polygon (no holes). Obstructions inside the room are not part of the outline; they are passive elements.

Placement geometry of an object within a chassis. Returned both in the chassis layout and as the chassisPlacementConfig property of a node.

Custom attributes defined on the object (including those inherited from parent objects).

Access rights the calling user effectively has on the object. Rights are resolved at the object in this order: if an access control entry names the user directly, that entry alone is used; otherwise the entries for all groups the user belongs to are combined; otherwise, if the object is set to inherit, the effective rights resolved independently on each parent object are combined. An entry granting no rights still counts as a match: a user entry granting nothing suppresses both groups and parents, while a group entry granting nothing suppresses only parents and the other matching groups are still combined. This is the same set of rights NXCP clients obtain with CMD_GET_EFFECTIVE_RIGHTS. Every right is always present as separate boolean attribute. Value is specific to the calling user rather than part of the object's stored state, and is ignored if present in a request body.

Placement of an object inside a rack or a chassis. Returned on nodes and chassis, and accepted as a merge-patch on the same objects: properties present are applied and properties omitted are left untouched. null clears the value only for the nullable properties containerId, imageFront, imageRear and chassisPlacement; sending null for position, height or orientation is rejected with 400. Always present on read, with containerId 0 for an object that is not placed anywhere.

Users or groups responsible for the object (the object's own list; entries inherited from parent objects are not included).

Per-poll-type state. Present only for pollable objects (e.g. nodes, sensors, interfaces); one entry per poll type the object accepts.
