* Closes #3329. This implements a new optional `cacheable` parameter for these REST endpoints: - `/rest/items` - `/rest/things` - `/rest/rules` When this parameter is set, a flat list of all elements excluding non-cacheable fields (e.g. "state", "transformedState", "stateDescription", "commandDescription" for items, "statusInfo", "firmwareStatus", "properties" for things, "status" for rules) will be retrieved along with a `Last-Modified` HTTP response header. When unknown, the Last-Modified header will be set to the date of the request. Also only when this parameter is set, and a `If-Modified-Since` header is found in the request, that header will be compared to the last known modified date for the corresponding cacheable list. The last modified date will be reset when any change is made on the elements of the underlying registry. If the `If-Modified-Since` date is equal or more recent than the last modified date, then a 304 Not Modified response with no content will be served instead of the usual 200 OK, informing the client that its cache is still valid at the provided date. All other request parameters will be ignored except for "metadata" in the `/rest/items` endpoint. When a metadata selector is set, the resulting item list will be considered like a completely different resource, i.e. it will have its own last modified date. Regarding metadata, the approach to invalidating last modified dates is very conservative: when any metadata is changed, all cacheable lists of items will have their last modified date reset even if the change was in a metadata namespace that wasn't requested. This also implements the abovedescribed behavior for the `/rest/ui/components/{namespace}` endpoint, but no `cacheable` parameter is necessary. The last modified date is tracked by namespace.
