VectorFeature Search

[BryonLewis]

• Adds bounds to vector and raster map layers, that are calculated on import
• Bounds calculation for zooming will now use stored bounds if they exists
• Update the metadata filtering endpoint to accept a bbox string and use that to filter out data if it exists

TODO:

• Update MetadataFilter bounds to have a refresh key or automatically update as the user moves around (throttled of course)
• Update the test.json dataset with some filtering metadata so it can be used for testing purposes
• Finalize the VectorFeatureSearch interface for declaring a searchable set of data for vector features and indicating what is displayed and the actions that occur when a user clicks on a dataset (one such action will be zooming in and then going to the metadata filter for filtering purposes)
• Implement client editing for the vectorFeatureSearch
• Implement endpoint for vectorFeatureSearch list.
• Add highlight capabilities/zoom

Configuration Model will be moved to a separate PR. This is a configuration to enable and disable specific features.
