Include Cesium viewer settings - MapSettings plugin

[allyoucanmap]

Description

We should implement a plugin component called MapSettings that will be injected in the Settings plugins and should allow to configure some options related to the cesium map.

The expected options should be:

• showSkyAtmosphere true/false
• showGroundAtmosphere true/false
• enableFog true/false
• depthTestAgainstTerrain true/false

It would be nice also to include lighting options but this needs additional investigation because probably settings true/false is not enough (eg do we need to set also date time?). This options should be discussed before to develop it because we need to understand if it's feasible in this task or need a separate issue

• enableLighting true/false

Acceptance criteria

• if a user select an options in the settings it should be applied directly to the map
• this options should be stored and added to the saved/exported map
• this saved map options should be applied once the configuration is imported/loaded again

Other useful information

• The Identify plugin has an example on how to inject a component inside the settings plugin (maybe we could avoid the array using fragments)
  

  MapStore2/web/client/plugins/Identify.jsx

  Lines 300 to 307 in 33bcede

  	Settings: {
  	tool: [<FeatureInfoFormatSelector
  	key="featureinfoformat"
  	label={<Message msgId="infoFormatLbl" />
  	} />, <FeatureInfoTriggerSelector
  	key="featureinfotrigger" />],
  	position: 3
  	}

• exported map contains a mapOptions key already but we should investigate on how it behaves compared with the other static mapOptions configuration in localConfig.json (eg it has priority, it split map options by library type, ...)

• saveMapConfiguration is the function used to format the final saved map config

  MapStore2/web/client/utils/MapUtils.js

  Line 485 in 33bcede

  mapOptions: currentMap.mapOptions || {}

• The mapsave selector it could be useful to understand other function that compose the final saved map object
