allow supportedQueryFormats override from metadata

[rgwozdz]

The GeoServices output now delivers layer metadata with the supportedQueryFormats field assigned a value of 'JSON,geojson,PBF'.
When PBF is one of the supportedQueryFormats listed in layer metadata, many ArcGIS Clients will preferentially make query request with pbf as the desired format. This is great because PBF is more compact, but some developers may want to force the use of JSON format by said clients (e.g., it might help in debugging). This PR allows provider developers to override the default value of supportedQueryFormats, by adding their own key-value entry to the metadata object found on the geojson generated by a provider. For example

const geojson = {
  type: 'FeatureCollection',
  features: []
  metadata: {
    supportedQueryFormats: 'JSON'
  }
} ;

This pattern would ensure that the layer-metadata would only list 'JSON' as the supported query format. So clients would then request in format JSON as opposed to PBF.
