Allow default resource metadata to be set in the model

Provider instances have the ability to independently set metadata values, however in most cases metadata is common to all instances of a model and it is relatively static. It therefore makes sense to be able to define default metadata at the resource model level which is applied to the instance when it is first created.

Note that only the Extra metadata is used to populate the defaults. This prevents other data about the resource (e.g. the resource type and value type) from being added and bloating the metadata. To differentiate default metadata values from metadata values which are set later the default metadata values will have no associated timestamp. This is in line with the behaviour for default resource values.

Fixed provider snapshot filterEmptyServices to keep services insertion order
 (commit: 202312d)

Implement the expand query for SensorThings northbound

This commit adds a backing implementation for the expand query for the SensorThings REST API. This is a pervasive change which requires us to carry context throughout the query so as to attach additional data structures based on the filter content.

* All queries now use full ProviderSnapshot instances so that we don't have to re-query for other resource data when filling in expansions
* Limited bulk data is included in expansions to prevent the JSON size exploding
* Data context is mapped by id to ensure we can expand values in lists
* All context is carried outside the DTO to avoid unnecessary fields appearing in the JSON output

Note that we require that all ids are able to be turned into strings. This is currently true throughout the gateway.

Allow data and metadata update de-duplication

This commit adds a DuplicateAction to the pushed updates, which determines the behaviour when the pushed update contains a duplicate value or metadata value. A duplicate value is determined by object equality, or == if one value is null. The default for resource values is that duplicates updates are applied, updating the timestamp and generating a update event. The default for metadata values is that duplicate updates are ignored, avoiding timestamp updates and update events. The reason for this difference is that repeated data readings can often give the same value, but this is a new reading. In general metadata values do not change, and so duplicates aren't interesting.

Annotated DTO mapping error

String fields annotated with @Resource and @Metadata caused all mappings to use the metadata value as the mapping. This should not happen!
